I have a 05 lt I do not have that on my truck I keep going to get Dino tests done they keep saying my mass airflow sensor is bad I can't find it

I have the same engine an yet mine has no maf sensor

I wonder what codes did you get to come with that repair. When mine do that uneven idle I clean the throttle body cause these models suck oil fumes thru air intake. And every time I clean the throttle body it comes back steady

Apparently, some have maf sensors, and some don't. Mine does not.

You’re awesome for this thank you!

Thanks! Do you push or pull on the tension bolt?

Thank you for telling me where those 2 parts are located. Being a female, men will try to take advantage of me even though I worked in the automotive industry for 20+ years and many shop owners have told me and given me an area in their shops to work on my own vehicles.

MY 4.2 L I6 2005 model year does not have one. Only one temperature sensor further along that air hose. Two people on the internet said it was eliminated as a variation in 2005. THE one I Bought from rockauto is going back. Thay said it would fit my vechicle. This really is true?

This helped alot thank you

Very helpful my vehicle was doing the same thing. Thanks for making the video!

My 2005 4.2 doesn't have a MAF sensor, just IAT and MAP

Thank you very much, this is exactly what I needed for my 03 pilot! I really appreciate how patient and clear you were THANK YOU!

Do both belts have a tensioner or do you need one of those belt stretch tools?

Get it all into the video ready to see where my map sensor is and then he goes since it's a V6.😂

My 04 envoy has a mass air temp Sencor which is round bout 3/4 round & about 2/1/2 to 3 inches long , mine isn't flat like that , not sure what they change stuff ? Same motor & everything else on those car are interchangeable

I’m trying to replace the tensioner on 04 pilot can’t seem to find the bolts

Also a note here, Buick Rainier, GMC Envoy, Chevy Trailblazer, and Isuzu Ascender are all the same vehicle so this works for all of them. My Ascender is at 227k miles and is having this issue to the point it surges like a cam and frequently dies while decelerating unless I apply throttle while braking.

Thank you!

You can pick up a cheap scanner at harbor freight for 20 bucks that will scan all your codes OBD2

Good job 🙏

oorah sir thank u!

Thanks for the advice how did you change the power steering belt if you have ?

Nice👍🏿 And your 200,000 plus miles & she's still running nicely! I found my 2005 up in Canton Georgia & little old man drove it & it was garage kept & she is clean on top & underneath! I changed the shocks & struts. On my second oil change to Mobile Super with all Wix filters. Fresh set of AC Delco Iridium plugs & the originals were still in the engine & none fouled 😁. Put a new Dynomax Muffler to free up the exhaust but not like a Flow Master🤮. New Tires 255/70 R16 & now I have to change the RR sway bar end link but I'm gonna change the driver side too. All in all it's in really good shape & I'm just replacing & upgrading OE parts because of age & not wear'n tare. It basically was a grocery getter! I got it at 124,000 miles last year & she's just at 133,500 since I've had it. Love these 4.2 Ltrs🥰. Stay safe & thanks for the video ✌🏿

02-05 Trailblazers do not have the maf sensor but an intake air temp sensor as well as the map sensor.

This video just saved me hundreds of dollars

I have on 05 trailblazer. Sometimes just turns off after backing out of the driveway and switching to drive. Starts right back up no problem but turns off as if you turned the key off. Think this would help?

Why should the guys at Autozone get into a grown man’s vehicle to plug in a OBD II scanner????

Thanks for the video. I have a 2002 and have never had this done. I'll be online ordering soon

ROFL

TY.. You have been a great help. I was having issues finding the MAF. You are right everybody says the MAF doesn't exist. GREAT JOB!!! I'm a female , and it will take me no time to do it.☮️❤️🕯️

Its called a torx bit

Very helpful video even for my h3 ive spent almost 3k in repair and ended up bein the maf sensor

Early model trailblazer doesn't have a maf sensor

Customers cars aren't sanitized If you plug 🔌 it in for the they shouldn't have a problem

Thank you very much the information I saw a video earlier this guy talk about using some kind of spray stuff on how to clean the mass airflow sensor

My 02 envoy doesn’t have a mass air flow sensor....

If this doesn't work for you, (and you can run codes), try looking at your Evaporative Canister vent Valve back near your differential. They are about $17 at rockauto and are a VERY common issue on these and their running quality. Would also be seen under fault code p0014. Try replacing those if you never have.

Thanks for this video much appreciated

I have a similar issue with my 04. But it only hesitates (RPM fluctuates about 200 RPM) when in top gear 70-90 Km/h. No issues on high speed or idling. Any suggestion will be appreciated.

It's dependent on the year. My 2004 LS has an IAT and Map only.

I recently changed my spark plugs but my car still turns off when in park or stopped at a red light.. I found my next project! Thank you for sharing your knowledge! 💯

I love when I come across a video showing me exactly what I’m needing to know. Thank you for sharing! :-)

...and yes, I did have the motor mounts tested and one replaced. It made no difference in the rough idle prior to replacing these parts.
