Chevy Trailblazer Runs rough, stalls P0014 

Thanks for watching and commenting

Glad it helped

Thanks for watching and commenting

Could you explain the three pushes on the accelerator please? Thank you so much!

update the engine blew a day later so i dont know lol

Yea these like other engines do have some issues . Thanks for stopping by

Rail rider mine got close to 250 not one leak anywhere

Same

Guys be careful. Ours had 250k and always used Mobil one full syn extended since first oil change. Never used oil, never a drop on the ground, never smoked, had oil pressure, and was taken care of and just threw these codes. It had never used oil and my dumb ass didn't check the oil like a should. It threw these codes and make a knock and I parked it. Mechanic said there was no oil to hit the dipstick. THis is my fault for not checking, but I had a false sense of security because I took care of car and it showed no signs of low oil. He says car is ruined. I am so sick right now. I just had to use this and a learning experience and not beat myself up to bad, but I deserve it. I should have been checking the oil weekly if not daily. My father always taught me to do this and I would say my cars don't use oil. He blew the seals in a truck one time putting to much oil in and I gave him a hard time. Well, jokes on me now.

Damn do you still have your tb?

ok

😂

My fuel gauge just quit. It has gas but of course I’ve no idea when it’s low if I don’t remember to change the mileage numbers and I forgot!

Thanks for watching and commenting

ok

6.6

Britec09 It was a easy one.

I do not , but Should be able to find the correct size at Napa , or if any engine machine shops are near they may know and have them . Depending on which one as there may be a few different sizes in that block . If you can get to it enough you maybe able measure the hole , with out removing the old one.

You read my mind. I cringed when he done that.

Rusty Glovebox Thanks for stopping in

drvshaft drew yea , when i see a oil reminder light on , my first thought is checking the oil because it tells me it has been in there for a while and most people never check their oil.

Hoping your engine is ok , but knocking does not sound good

CHOPSHOPUNDERGROUND This one does not seem to leak , except for the valve cover , plug holes fill up. Gas gauge just does not work.

CHOPSHOPUNDERGROUND oil pressure is amazing John lol

More350Power I see you had to make a oil pressure joke. LMAO!!

Oil around spark plugs is usually a valve cover gasket . Takes a while to change the gaskets

Best thing to do is put it on a diagnostic scanner . Have you checked fuel pressure . Is it al the cylinders or just one or two. Usually a flashing light , can mean if still driving it can damage the cat converters If you know spark is good , compression is good then maybe fuel system.

and when diagnosing , remember , a coil , fuel injector , compression , things like that are usually what affects one or two cylinders , where a MAF cam or crank sensor fuel pressure would affect all cylinders pretty much the same . O2 sensors , depends on how many banks . , but if a 02 sensor goes bad it affects the whole bank , not just one cylinder.

I do not remember right off , but some have a grey lock that needs to first be removed , before squeezing the tabs

Glad you got it fixed and thanks for commenting

What sensor do are you referring 2 ?

It could of been dirt that stuck in the vvt solenoid . If the engine runs and nothing malfunctions again for so long , a lot of times the light will go out , but will be stored as a history code unless erased .

Those trailblazers take 7 quarts by the way every oil change 7 quarts new good filter not a shitty Bosch or Walmart brand fram or k&n is the way to go itll be $8 or more for the filter but itll do you wonders if you put new plugs in only go with autolite double platinum or ac delco plugs no cheap or any other brand trailblazers don't like just any spark plug they're picky and eventually if you have to replace ignition coil packs for the plugs use drivestar unless you can afford delco they get pricey 44 each on Amazon 6 ok of drivestar are 76 for the 6 of them and my trailblazer loves them every 6000 miles run a can of seafoam to 20 gallons of gas injectors cylinder heads u name it will love you for it and never fall for the cheap $19 oil change shops buy your own get good Castrol edge advanced full synthetic 5 quart jug plus 2 additional quarts you'll see a huge difference in performance gas mileage u name it that's what I've done and she's treated me phenomenal

@@matthewbrady1617 i used ac delco

Traction control . Check abs sensors and wheel bearings . Is where i would start . If could get car scanned it would give info also

ZIGgassedUP and you would be Right

If you unplug does it start again . , Need to see if you have spark.

If you are talking on the dash , it works on oil pressure and still enough pressure to keep the light off

Mine's never came on when I was low on oil

sixtyfiveford Thanks

Thanks for watching

Good it was not serious

Always check not running , Cold if can , but if engine is not slugged up in side and at operating temp , only takes a few min for oil to drain back , it has a full tank . Sending unit in tank is bad , like a lot of them are and customer does not want to fix it

Could be the battery connection or at the alternator

That is not to bad depending on where you live

They finally did fix the fuel gauge

Yea the pwr steering is the worse part , but not to bad of a job . Thanks for stopping by

not mine and no fuel in oil

Check and see if the throttle plate is dirty

if oil is clean or just changed and the right weight oil for it , and full , then it may be the Camshaft Position Actuator

Check if leaking where reservoir mounts on pump . sometimes that o ring leaks

maybe bearings

I would not run with out a screen .

Not sure , but would look at some wiring diagrams of those systems and see if use the same power , ground or tied together in any way . Find any of their common points and start there

Yaheuben66 Hello have ya been out driving

Thanks for stopping by.

zx8401ztv Most people do not check anything , unless it causes a issue.lol

wtbm123 Some people need a good slap ha ha :-D

A lot of them have leaky valve covers and can leak a lot fast.

@@wtbm123 Thank you for responding. We keep it garaged and there was never a drop of oil on the ground. I have to deal with the car being ruined, but I also want to make sure this never happens again. I always used Mobil one Full synth extended and changed oil@5-7k miles. The filter was small for 7 quarts. I will be ultra vigilant on my next vehicle. Will be check the oil weekly and probably daily at first. I want to find a larger filter too. The envoys filter was tiny and the price for a good one was high. Wish the car had been LS style motor. Our truck has the very first one they put in a truck 99 LM7 it has 450k miles and still pulls strong. Great engines. I like the tall skirts on the top of valve. The cover is tiny and flat.

***** the engine still had some oil pressure , but not the right amount at cam solenoid.

never said it was to check the oil

Yes oil changes are very important these days

Hope it helps if not may need to test and replace the vvt solenoid

I believe it's your actuator on the transfer case. Look up trail blazers on Utube...many vids on every thing. About a $90. part and no big deal to replace...they seem to get stuck from non use.

If it ran ok after cleaning , may clean again , if there is a lot of blow by it may get dirty quick , also check for oil around the spark plugs

scottsinfl When low sometimes the right oil flow, and pressure is not at the cam position solenoid , and it does not do the timing right , but not starve the engine of all oil pressure. , but is enough to throw off the cam timing . the oil pressure switch never showed no oil pressure.

Cam position sensor or solenoid

Regular Oil changes would do wonders for these

Easier to get in and out , but harder to see for me . Thanks for stopping in and commenting

Yes , that is also true to many new engines

@@wtbm123 right 4200 vortec can last long time to, good maintenance 👍🏼, I have two, SS and LS TB, I rebuild everything.. runs good smooth with new body mounts to

Is there oil leaking in around the spark plugs , or something causing a vacuum leak . Is bank 2 data readings good or are they showing lean also but not enough to set a code for bank 2 . if so may do a fuel pressure check

kinda sounds like bad cat.

Could also be a dirty throttle body . Best to hook it to a scanner with live data to see what is wrong

Hello , did you get a fix? Thanks

Because fuel sending unit is bad . Customer knows , but did not want to fix.

mine reads backwards lmao. empty is full and full is empty. my grandma got in and said *oh my we need gas* then i explained it to her

FYI: even with this code. The blazer is running super smooth. In the 10yrs we've had it, it hasn't run so smooth before. So, I'm stumped. I did just replace the valve cover gaskets. The shop did it 2-3 yrs ago. It began leaking real bad shorted out a coil pack causing a cyl. 1 misfire. All the spark plug bays were filled with oil. I sucked out the oil, replaced plugs and cyl 1 coil pack. I found one of the valve cover gaskets that goes around the plugs was missing. So, I have new gaskets all around. Get it all back together and now the P0014 code hits.

The Camshaft Sensor Solenoid very well could be it . Unless very low on oil at the time it is usually the sensor screen that plugs or gets something stuck in it . Need to loosen power steering pump , to change it , but not hard to do , and not to costly . So yea it is prob the next likely thing .

Check the muffler bearings

You need it if you do this everyday . Good ones are twice that much

That dipstick is about worthless ,

some leak and some burn some , but not enough to smoke out the tail pipe always .

Yes there is

Properly maintained they are very reliable. Saw one recently with over 300k on it for sale at a Honda dealer it was so clean. Trade in. I have an 07 Trailblazer with 105k on it and have stuck to its maintenance schedulento the letter. Id take off to California in it tomorrow!

tlcbear2

We have an 07 Envoy 4.2 with 135k miles and it's very reliable. People that have problems with these vehicles just don't maintain them.

sending unit in tank bad

+Abraham Brown Sometimes the solenoid needs changed to fix

+Abraham Brown Well there are a lot of additives , but i can not recommend any . Rislone makes one , but if they let chunks come loose and float in oil , may go in bad places , but may also work just fine . Plz let us know if you do use one if it helps or not .

+wtbm123 I don't know which one to use I was looking to see if I can find something to use

They make easy out sockets

snocrushr yes

Thats exactly why I always try to do all my own maintenance and repairs

Sometimes yes , most times they seem to act up again soon . But not to hard to get to if wanted to try cleaning

Generally when they start showing signs of oil around the vvt then it’s time to replace it...clean it periodically with brake clean and check it over..make sure all the screens are intact and nothing clogging it..it should be fine..this is my personal experience from the past two years on a used one I pulled from a scrapyard...but if u do replace it with new..eBay or rockauto sell them for so much less then the local parts stores do..and it’s so easy to replace it’s almost a crime for what the mechanics shop charges for the swap ...

@@w8what575 thank you for the information I appreciate it

Is the check engine light on . It is hard to say with out testing . Is fuel pressure good , Is the vvt solenoid good , Hard to say with out testing

wtbm123 no check engine light. I haven’t gotten around to testing the fuel pressure yet. How do you see if the vvt solenoid is bad?

@@Will-ot8wi Hard to tell with out some way of seeing live data , but thinking it would set a code if it was bad . It is the valve behind the PS pump. With out being able to see live data , it is hard to work on newer cars

wtbm123 I know WHAT the vvt solenoid is but idk how to check it. I don’t have a fancy code scanner that gets deep down into everythingz

@@Will-ot8wi Some of the ones that plug in and use your phone to see data can help , and a lot of the new cheaper scanners have live data . It is just hard with out live data , and still hard at times with live data . Hope you get it all sorted out

It was a customers car , so not here now , sorry

if oil is ok , then prob the camshaft actuator solenoid. sometimes the screen gets plugged , but usually cleaning only works for a short while if at all . Make sure the oil is clean if replacing . behind the power steering pump . have to loosen the pump bolts so it slides a bit out of the way . That would be my guess if oil is good

I bought my trailblazer 2 years ago running on 3 of 6 cylinders..I got a vvt solenoid..the camshaft solenoid he mentions located on the passenger side of the block behind the power steering I believe...from a scrap/pull ur own..yard..cleaned it with brake clean and it’s been working great for two years now...it’s about time to take it out and clean it and check it over...these things break down so easily and have so many design flaws or factory defective parts that I tend to carry an extra of certain things like coils..belt..vvt...things like that...but being stranded on a Friday night and no parts yard open till Monday sucks! Lol

TheEZGZ and hard to read

I usually get redone clusters from the parts store . One can get the stepper motors and hope that is all that is wrong. But by the time i get parts , charge labor , i can get one for about the same price for the customer . If doing for your self it would be ok as you would not have the labor charge

I agree

Steve Rob The better you keep them the better they last.

That means reduced engine power newer cars kinda do that now if there's a severe problem it might have been that where the solenoid wasn't doing what it's supposed to

Thank you for answering

+TimsComputerRepair Oil is a good thing

+wtbm123 lol! yes... yes it is.

TimsComputerRepa

not mine , but they do know it needs fixed . Not sure if they will though .

Would need to have a shop diagnose it probably . could be a number of things

had that problem when my battery needed replacement...fried the cluster too

unplugged mine 🙄

Jorge Narez lol man i only get 17 on a good day!

CamperMike It is a oil change reminder , so when you see that the oil has been in there for a while and may or may not have been checked in a long time . So a good place to start.

wtbm123 I too, thought the oil change reminder light was solely for this purpose. Had no idea this light could trigger codes.

Stanley Waggoner I never said the oil change light , triggered any code . It is a clue that the oil is old ,and may not of been checked in a while . It is a clue only.

wtbm123 I see.

It may or may not fix it . Sludge Is hard to completely remove . Also there is a Variable Timing Solenoid , that has a fine screen on it . They sometimes get damaged and plugged up . It is kinda above and behind power steering pump. They are not to bad to replace if needed

@@wtbm123 Roger that. Yes they said it was the Variable Timing Solenoid that needs replacing. I have been driving with the light on for about a month and a half now. I hope it will hold up until I can get it fixed. Thanks so much! Your channel is awesome and you provide some invaluable information. Thanks for all your help.

@@groovy777 did you get it fixed?

@@novisoprano1420 I unfortunately didn't get it fixed until last month. By that time, strangely, they said it wasn't the solenoid that needed fixing but the Vent Control Valve as well as the engine coils and spark plugs, which was much more expensive. I'm wondering if the solenoid problem progressed into these more advanced issues as time went on. The check engine light went off for a while then it came back on so it was a bit confusing.

@@groovy777 yeah my Engine light came on and it reading that same code and thinking about buying that part and fixing it.
