Here's Why You Have POOR IDLE In Your Car Or Truck!! 

😂 thanks! Yes, it’s pretty clean.

@corey Babcock my truck does not have a EGR it has VVT(LIVC) which is way better then a EGR 50% less emissions then a EGR vehicle

He's changed everything on it---it should be clean!

Its in the middle of the annual dirt replacement due about this time

@@adsbadsb9488 Most gas powered vehicles don't perform well in the cold. If you believe the EGR is original equipment, it's more than 20 years old. Just replace it. They don't cost much.

Wow, thanks for the great comment!

Thanks!!

I have a ' 95 g-20 van. Same engine. I had a '88 K-5 blazer ..same engine. These vids are helpful.

Thanks!!

Preventative Maintenance

Thanks! Yes, I’m kind of excited about truck camping! I’m also wondering if my fuel mileage will slightly increase with the EGR now fixed..

Make a block off plate for your EGR and your millage should increase some. Particularly if yours is sticking. Hot nasty gases going into your engine is a bad idea from day 1 for engine longevity, fuel efficiency and performance. The EGR valve should only be open at idle and deceleration (high manifold vacuum). If it's sticking intermittently and random, that's a bad situation all round. As a minimum, replace it so it operates correctly. 2 bolts and a vacuum line or electrical connector. Not very expensive, gas is. Your engine will thank you.

Thank you!

I have a misfire/surge every 10-20 seconds at idle when my 92 5.7 is fully warmed up.

Thanks dude

Because nowadays to need the computer to read the data and see what isn’t right. Your supposed to verify what is actually causing it instead of just throwing parts at it. Some bad mechanics do throw parts at it but the fact the you think using a computer to check what’s wrong somehow makes them look bad show that you have no idea about what’s going on in modern cars

A bit late to this, but your comment hits paydirt with me. 1989 K1500 5.7. Engine pings under load. Check vacuum, only 10". Tested EGR and pulled it. Looks okay. Pull the intake manifold and discover the EGR passage is totally clogged with carbon. You cannot see this by pulling the EGR. Jamming a screwdriver into the intake to clean the carbon, not good as carbon will fall into the engine. EGR needed not just for emissions, but to help prevent pinging. Not sure how those who delete prevent pinging?

👍 Good to know!

So why not simply replace the part instead of waiting for it to fail at the wrong time and place?

@@scout4locations because it's not necessary to replace it. A failed egr isn't going to leave you stranded. For years my dad just removed and blocked them off because they don't make an engine run our run any better.

@@duckwacker8720 if the valve sticks half way open or more the engine won’t idle at all or start so It can leave you stranded although not very common

The EGR valve is part of my smog system and is checked when I get smogged thus I can’t remove it.

@@1RoadGarage Not saying remove it. Just slip the relatively slim sheet metal block plate between the gasket and EGR valve and reinstall it. You can take it back out before you take it to Gestapo smog inspection in Cali if you want but unlikely they will even notice it. It will have no effect at the exhaust pipe if you have good cats. NONE. I have done this with several cars in Cali, never an issue. If they do see it, just say a previous owner must have done it, take it out. Put it back in when you get home. Look in the manifold were EGR mounts, all that black carbon is bad JuJu for your engine. Most of it goes through your combustion chamber so what you see stuck in the manifold is not near all that went through your engine. EGR's had some minor affect on emissions on carbureted cars (particularly at idle) but EFI (including TBI) runs so much leaner and cleaner EGR is not really doing anything but clobbering the most important moving parts of your engine (pistons) with terribleness (abrasive debris). Voluminous microscopic chunks of hard carbon in your engine is good for mechanics and dealers but not engines.

I think it would be easier to just buy the gasket material and make your own, accidentally forgetting to make the holes on the inside of the gasket. Nobody would ever know unless/until they removed the EGR valve.

@@fredflintstone4715 You'd have to use asbestos or it would burn through in no time. If you use 18-20 gauge sheetmetal, you can make it slightly smaller than the gasket and body of the EGR. It would be almost impossible to see without dismantling. Another thing you can do that's really easy is get a golf tee, cut it in half, use the pointed end piece to block off the vacuum line.

That's what my dad always did. I've done the same on the few egr cars I had.

Even more beneficial on a Diesel as diesel soot is abrasive

@@SlingSalsa all soot (carbon) is abrasive.

@@SlingSalsa it’s more beneficial due to the higher cylinder pressure,turbo induction and mileage expected from a diesel.

@@NoName-tz5ji yup anything to get a better scavenge ratio, and you see better gains due to the higher energy density of the fuel etc...no other service vehicle has practically given me money back like that truck, or any car I've ever worked on has given me giddy giggles and smiles like that truck does. I look forward to getting a cam and having the stock heads ported when I pull the motor for a refresh. 728k miles on stock trans and head gaskets.

If he’s in commiefornia ,he won’t pass the visual on the smog test even if he passes the sniff test without it being there and hooked up.

@@NoName-tz5ji you have to leave it plugged in and sitting there so it looks like it's installed still those California guys got ways to get around all of it friends in the shop or something like that.

What do you do when the check engine light comes on? What does the computer due to fuel management when it detects the system isn't functioning?

I agree throttle body injection far better than todays crap

But.... bad news later on the engine spun a bearing or had like bad knock an what happened was the onwer didn't chnage the oil after I replaced it an there as so much fuel in the gas it thined the out an that's all it took an basically destroyed the bearings .

@@jb9072 Thank you for pointing that out. I didn't realize these old systems were so complex.

I just got the same code in my 02 avalanche. What did you figure out?

Yeah, because things get cheaper over time and more convenient 😂

Is that a Ford 5.0?

@@1RoadGarage yea in a 81 ranger f150

Every idle problem is not EGR related. Check your plug wires for proper seating on plug and distributor cap, particularly if they were recently replaced. You install cold wires on a cool engine. When it's later run, any air trapped in the plug wire boots at either end of the wire expands and can pop them slightly off the connector. You may hear them snapping, particularly on cold start up. I've had this happen several times. If they are all good, pull your plugs and recheck the gaps. NEVER install spark plugs without very careful gap setting. It DOES matter. If you can't locate the EGR valve on your engine, buy a Haynes manual (or equivalent) for your specific vehicle, about $15 at any auto parts store. They aren't great for everything, but basics like EGR location and tons of other things you'll need to know, often a god send. It will be handy, trust me. You can also Google the EGR location but the book will serve you well.

My 97 Tahoe had 360,000 when I sold it to my buddy. I'd still get 20mpg at 70. My friends son drove it from Washington to Utah and they go to the place they were going 3hrs early. They parked at a restaurant and it started to knock. He ended up spinning a bearing.

@@duckwacker8720 Sorry to hear that I let a couple use it to go to Walmart this morning and they left about an hour ago.I didn't know Saw a bunch of crashes on the news and went to say no because of ice.They were already gone not answering the phone.Hope I get it back

@@duckwacker8720 Are you going to fix it

True

Have you ever seen how strong the spark is that comes off a stock coil? MSDs are pretty, but I'm trying to imagine an aftermarket part made by anyone that lasts longer or is more dependable than a GM factory part. Break down in small town USA and try to get an MSD distributor cap. 😁 I might buy a couple stickers to put on my window. 😁

I needed both on my 95 used to run rough, new egr made mine worse till the solenoid.

​​@@justinwoosley3188What solenoid? Do you mean the electronic-vacuum solenoid used on cars with the hybrid electronic pilot valve/vacuum EGR valves? Or do you mean the idle air control servo?

Diesels have them too. They started getting them about 2001

VGG 😂😂😂 hood one

Good

Good to know, thanks!

This is a very bad idea. That carbon is very hard and brittle. You sent shards of abrasive into your engine. They will go right into the cylinders. If the hole is blocked or mostly blocked, leave it that way. EGR is a bad for engines. If you are driven to clean that out, remove the manifold from the engine first.

Another Fun Fact and Pro Tip: The EGR is the reason why EGR-equipped engines get better fuel economy at highway speeds. That’s when it’s functioning the most. When cleaning or replacing the EGR, inspect the port(s) feeding it. I once had a GM 3.1 MPFI with the supply port completely clogged and 3/4” deep with carbon buildup.

That's too high on an EFI Chevy engine, 600 when in closed loop. In both Park and Drive. You could have a sticking IAC (Idle Air Control valve).

Mines a manual transmission plus it's also stroked to a 383

@@stevehopkins8902 Stroked wouldn't by itself have any effect on idle. It is electronically controlled. If it has a lumpy cam you'd have a lot of re-tuning to do for all ranges of driving. But if you are running the stock EFI with stock tune, you should be idling at 600 when fully warmed up. Even with manual trans.

@@x-man5056 the tbi is an Holley 675 bored out to a 750 cfm with a custom tuned ecm out of Caldwell ID

@@stevehopkins8902 If somebody went to that much trouble I'd guess it does have a cam in it. 750 still seems a bit high, particularly with TBI or EFI. If it's stroked and camed it's a wonder you even get 10mpg. But bet it's fun.

Haha 👍

A lot of the 5.2 and 5.9 magnum v8s didn’t either
