Sorry for continuous posts on this issue but have finally figured out the issue. Just need help with a solution.
The EGR has been deleted...Including the solenoid. This was done about 8 months ago and the car has been running fine during the winter. Now... It stutters while driving and is throwing out Code 32, which I know is the EGR. Unfortunately the car is stuttering while driving now in the summer...I live in Colorado, so Im making a broad assumption that the 90 degree weather is whats making it have the issue now. After a bit of research I saw an individual have the same problem, but his fiero was throwing out Code 42 as well, and I mine is not. So I cant follow the solution for that thread. I learned that If you splice the two wires together (from the solenoid connection) that go into the vacuum link, it will stop firing off the code. Is this a passable solution until I can afford a chip that deletes EGR function? And if so, which of these two wires of the four are the ones I need, since I cant seem to find a diagram detailing this.
(All vacuum lines are hooked up correctly. Triple checked to make sure)
We used a piece of sheet metal and slightly overlapped the edges, then used the EGR bolts to secure it in place. It looks fine but Ill take it off to check.
I pulled and replaced the spark plug yesterday. I used an Air Compressor to blow out the debris and the plug came right out. Its in securely now. As soon as the car "stutters" the check engine light pops on and throws the Code. As soon as the code comes on Ill park the car and leave it on ACC mode and it pops 32 every time. This issue is a nightmare and the bane of my existence at the moment.
You need the EGR delete chip. With the EGR removed, the engine is likely running way too lean, and with way too much spark advance. This, based upon the EGR ON vs EGR OFF tables that I've seen. Adding the jumper will just make the light go away. It won't fix the problem. You could burn pistons, runing it that way. Please don't think I'm an emissions nazi. I really don't care. But if you're going to delete it, you need to do it right, and not half-azz.
Ok. I will start looking for the delete chip than. Thats more or less what I wanted to know. I dont want to ruin anything any more than it already is so Im gonna hold off on driving her until she gets the delete chip. Thank you!
If you blocked off the egr, you want the code to come on so it doesn't try to go into egr mode.
To explain even more when you are cruising and the egr conditions are set it will try to go into egr mode for 10 secs, when it can't it throws the code. as posted above it WILL lean out the car, thinking that egr gases are using up part of the cylinder space, thus needing less fuel. So you defiantly should not fake the ECM into thinking that it is working, you really need a chip.
What chip should I get? Ive only found one on reddevildriver but the whole "not meant to be installed" disclaimer bugs me. And am I able to do this installation myself. I have some knowledge of electrical workings, but mainly on newer cars. I redid the ECM on my 2012 Camaro but I dont know if his fiero is "plug and play" with this chip, or if I need some other tool to do so.
Send a PM to Phonedawgz and he can explain how the chip should be used. The car is supposed to have pollution control equipment. If you are bugged by a little lawyer talk, I would recommend that you revive the factory EGR system.
Bounced off of a guardrail on the highway. bought a tire that ended up being trash, the tread separated from the tire and the car did a 180, slamming the passenger side against the guardrail...surprisingly only needed to rewire the lights and buy a new panel, frame and motor were good but it destroyed the valve... Somehow... So we just took it off and sealed the y pipe, then removed the solenoid... This was before I understood as much about this car as I do now. Unfortunately funds are ridiculously tight for awhile and I cant afford the $120-ish to replace them both. Or I would. I cant wait two weeks for a paycheck to get a new EGR setup... But I can afford a 50$ chip.
Disclaimers are intended to keep from getting sued. Operating on US public roads with the chip installed is a violation. The chip is intended for people who do not operate on public roads or do live in a country that allows it.
Yes, you can install it yourself. Disconnect the battery. Remove cover to the ECM (2 screws). Carefully pryup the carrier of the existing chip. Insert the new chip/carrier. Put the screws back on the ECM and reconnect the battery.
The chip works by altering the conditions required for the ECM to activate the EGR system to parameters outside of normal and even abnormal engine operation. Thus the ECM never calls for the EGR system to be activated. Since the EGR system isn't activated the timing and mixture changes the EGR system requires for are never changed. You will not get a code 32.

And alright. Well Ill get the one on Red Devil River than. I know I seem like the biggest tool right now 😂 Go figure... I can rebuild a 1972 Firebird but I cant get a damn fiero to cooperate haha
