Once it is started, how does it run cold? Then, how does it run when warmed up?

Re: 1988 camaro check engine light
Sounds like you may end up changing the IAC (Idle Air Control motor). If you do, use some Valvoline Syn Power throttle body & carb cleaner in the bore where the IAC sits.

Re: 1988 camaro check engine light
ok i did the egr checks and it either has to be the diagnostic switch or a bad solenoid. so i will change the solenoid first and see if that is it but will be a few weeks before i do that cause that piece is kinda expensive lol. so will let you know. thanks april

No problem, we'll narrow it down further and cheaper. take the line going to the EGR valve off and hook it to a vacuum gauge. Tape the vacuum gauge to your windshield and go for a drive. Now, while driving keep an eye on the gauge and the check eng light. When the light comes on, look at the gauge. If it reads vacuum, the solenoid is good. If it always reads vacuum as soon as you start the car, the solenoid is bad. If the check eng light comes on and there is no vacuum reading, the solenoid is bad. If you need a switch you can get it from RockAuto.com for about $12 If you need a solenoid you can try checking the local junkyards, they usually charge about $10 for small parts like that...or if it happens to fall in your pocket.... Oh, and if there is no constant vacuum, then that isn't the cause for the low idle, its more likely an IAC. To check it, if you have working A/C, get the engine running and warmed up. Now watch the tach and listen carefully and turn the A/C to MAX cold. The engine idle should come up JUST before the A/C compressor engages. If it does then the IAC is working. If the idle won't increase or is slow to increase then try cleaning the IAC. You can pull it out and clean it with the Valvoline syn power TB & carb cleaner. That stuff eats carbon like no body's business. Just spray it on the pintle end (metal cone) and the shaft and spring and let it sit a minute and spray again. Then spray in the bore where the IAC was and let it sit and spray a few more times, then use an acid brush in there and spray it all out again. The IAC gasket will likely be trashed but you can make one from some thin gasket paper (auto parts store). To put the IAc back in. Hold the body in your fist with the pintle facing up towards your thumb. Now push down hard on the pintle with your thumb while rocking the pintle bqack and forth. This will retract the pintle and prevent you from jamming it in the bore when you reinstall it. Don't worry if it sounds like you stripped something out while seating the pintle, it is supposed to do that.

Re: 1988 camaro check engine light
ok it is the erg solenoid i will be calling some junk yards to find it. and for the iac i dont have working ac my bearings are locked on it. so cant sheck it but might go ahead and change the iac after we fix the egr solenoid. thanks for all the help you saved me a bunch by those sensors instead of the mass air flow. will let you know how it goes when i find one. thanks april
