Hey guys I wanted to know how bad of a job this is. What are the tools and parts im gonna need. I know I need the gasket if they make one and then after that Im not sure of what to do. It looks like I can just remove the two bolts and then pop it off and remove the egr. But there gots to be more to it than that. Please guys if u can help me out I would really appreciate it. The problem consists of the car trowing a code 32 once in a while when im cruising and then in the morning it shutters until warm and the idle is funny. I have checekd everything from hoses to adjusting the throttle screw. and it still idles funny. Thanx again guys.

It's that easy. Sounds like the egr is not closing all of the way. If you have the 3.1L V6 and are looking at buying a new Digital EGR be prepared to send a couple of hundred dollars. If it is a 2.8L you are lucky, the EGR for the 2.8L are cheap about $30 - $45.

 

I hope the replacement fixes your problem. I have an 86 Sport Coupe with the 2.8. SES light comes on while driving, stays lit for about 3 to 5 minutes, then goes off. Code 32 every time.

Hard to get started in the morning and idles funny. Also, mine wants to stall when stopping at the red lights. I've checked every vacuum line. I am probably going to follow the Haynes troubleshooting guide in their manual next.

I replaced the EGR valve. Pretty easy job. Two bolts and 1 vacuum line. The replacement from the parts store was universal and required a washer between the valve and exhaust manifold. You might have to write the replacement number on the sticker on top of the valve.

But, the change had no impact for mine.

 

You might want to check the EGR solenoid that has vaccum hoses coming from it and hooked to the top of the non-digital EGR valve. The part number for it is 14089438 and is about $65 from GMpartsdirect. This solenoid is ECM controlled and could be the source of your problems.

 

take it off, give it a good cleaning and put it back on.

By removing it you will lose around 10-15 Hp, and 10-12% MPG.

To remove is a no brainer, just cut a plate to fit the opening and bolt it down.

 

How will you lose horsepower?

 

I was always told that EGR removal could damage the engine. I mean it does recirculate exhaust gases which does lower the temperature in the combustion chamber so maybe that is the benefit.

 

Yep, it does put exhaust gas back in, and lowers the temp of combustion. High pressure + High temperature = horsepower = NOx for the smog police. The EGR kills the NOx.

But, EGR only kicks in at low-throttle, engine-warm, high-speed crusing situations, which you'll find when you're doing 55 on the highway on a beautiful sunny day with a hot chick next to you, and you're in no particular hurry to go anywhere. So if cooling the combustion temp were to help horsepower, you wouldn't notice, because as soon as you floored the gas, the EGR would shut off.

When EGR does kick in, it can also richen the a/f mix (decrease in oxygen due to added "dead" exhaust fumes will reduce the size of the explosion (lower temp of combustion) AND less oxygen = richer running). The computer is supposed to "know" this and leans out the injectors to compensate.

The argument is that when the ECM leans out the mix because it "thinks" the EGR kicked on, that if the EGR is removed, you'll wind up running lean. And that might lead to a pinging noise during those low-throttle high-speed situations. This is another reason why it makes sense to leave the EGR on- it doesn't make you slower because it only comes on when you're easy on the gas, and it helps the environment, and doesn't really bother anyone.

But I've never heard that taking the EGR off can make the engine lose horsepower. I've heard the motor might ping, but that's all. That's why I asked...

 

I am getting a code 32 as well. I hope it is the EGR valve not the other things in the EGR system. I plan to replace that and the TPS this week so if that fixes my problem I will post and let everyone know.

These are the last two codes my ECM is throwing out!

YAY!

 

to compensate for the ping, you need to retard timing, or risk melting pistons. less timing, less power.

 

I like melting pistons that sounds like a great idea.

 

Well if I melt them, I would like to do it for a worth cause, like going lean while running 15 PSI!

 

If I melted them I would like to have a spare engine in the garage.

 

Ah, okay, now I understand your reasoning!
