Ok, what would cause a code 32 immediately on startup??

Thanks

I have the same code on my 86. Code 32 could be 3 things: EGR Valve, Barometric Pressure Sensor Circut Failure, or a Vacumn Leak of some sort. My problem is that when the engine is cold, the car wants to stall(and does)very badly. Sometimes, it shakes violently. But my engine light only comes on when i am doing 65-75mph on a long drive..and stays on anywhere from 10min to 10 miles and then goes off...and never comes back on again. But as far as code 32 is concerned, its gotta be one of the above problems. Check those out. Good luck.

I guess I left out that I just replaced the 2 vacuum lines from the EGR Valve. I have triple checked to make sure they are on and in the correct place.... The old lines were broke and I was getting 32 only periodically like PHantom describes, now I get it immediately on startup.... Could I have damaged the valve from putting the vacuum lines on?? They were really tough to get on.

Well , I have been fighting with this since October, You didnt damage the valve by replacing the vacume lines , but thst a great place to start , I would try replacing the egr valve it self. It shouldnt be coming on right away after start up , the egr vavle doesnt start working until the car is moveing at a steady speed, like Highway driving, It could also be carbon build up in you intake passages. I see your car is a 92 ,, mine is a 91 , and i just got it back on ,, i think my problem is my exhuast is to free flowing , have you done any exhuast modifications of any kind?

scanman717

Yep, I did put a flowmaster 3" exhaust. I also just finished porting the plenum, and cleaned out the egr passages in the plenum. What confuses me is that when I had broken EGR lines I only got the 32 code after running for a while... I am almost tempted to take it off again and see what happens.

Yes, mine ONLY comes on when i am traveling at a constant speed, and on a long trip. I also have a modded exhaust, with a random tech cat(see sig)....i just hope this doesnt corrupt the EGR or anything else in any way.

well I'v been told that a negative pressure egr system can be converted to a positive system which would not need back pressure from the exhuast , im probably going to have it done next month or so , so i will let you all know what happens , I have replaced everything some things twice even and still get it , so this is my last resort.

The odd part is that I put the exhaust on almost a year ago and this just started...

Thats exactly what i did also , but the thing with performace exhuast , as they get older abd break in they flow better , and usually get louder, so thats why it doesnt affect anything until a year or so .

If your SEL comes on Imediately at startup with a code 32, your EGR diagnostic switch is bad. (this is the little feller that screws into the base of the EGR valve. Single wire connector) The only time EGR code will set as soon as you start up is when the switch is telling the ECM that EGR is open.... Generally implies a failed switch.

You probably just have excessive carbon buildup..... I had the same problem, and took the plenum off to take a look...both the egr passages were 75% blocked... So a good plenum cleaning with carb cleaner, and then spray the heck out of the runners, and you should be back and running....I did not even remove the EGR valve (which can be a pain with the sensor in the way), and really dumped a lot of carb/fuel injection cleaner down the runner EGR holes..... It would also be a good time to pour some GM Top Engine Cleaner down your runner openings.

I think my prob is more like the EGR itself is bad...anyone have a pic of what one looks like? And a diagram of where it goes on a 305 TPI engine? Thanks.

I was wondering,after having so much carb/fuel injection cleaner dumped in the runner EGR holes and also dumping GM Top Engine cleaner down the runner openings,did the car have a hard time starting up,cause all i can imagine is all the carbon and chemicles sitting at the bottom and covering your plugs.Thanks,Al in NJ

I just got a code 32 this morning. Replaced the EGR valve about a year ago. I'll check out the vac lines and that little wire and let you know what I find if anything.

A failed or disconnected temperature sensor can cause an immediate DTC. A failed EGR solenoid can as well.

Phantom,

my buddy has a TA that was doing the same thing that yours is doing. he tried going down the road & then yanking it off the road to punch the ALDL to see if he could not get the code but no luck. he ended up borrowing a scan tool from another budy of mine & had it sitting on the seat next to him. as soon as the CEL (or SES) light came on he picked it up & saw that the code was for O2 sensor. He did not think that possible as he changed it 4K or 5K miles ago. but he changed it anyway. He has not had any more CEL's since.

HTH's, worth a try if you dont have a scan tool.

Oh, & as for the shaking & wanting to die thing, I bet that if you use a scan tool that you might find that it stops shaking & starts behaving as soon as it warms up & goes into CL (or gets close to it). check to see what your IAC counts are. Mine were in the 190 range & it was doing a simlar thing. last weekend i took it appart & found it VERY dirty & crudded up. I cleaned off the pintle & seat & put it back together. set the minimum idle & now she purrrrrrrrrrrrrrrs.

just a thought.

First, let me say thanks to you guys. You have been a wealth of info.

Here's what I know up to this point... The Code 32 has stopped on startup. it now only comes on after highway driving. I do have a scan tool and verified that all parameters are in acceptable ranges. I forgot that I had disconnected the battrery and the computer needed to "re-learn" everything, and the car since purrs like a kitten.

My factory service manual suggests that I could have the vac lines pushed on too far, thereby causing a blockage. I am going to try this later today, as this is the last thing I replaced before all this crap started.

I will keep you posted....

i've done to engnes in my cars one in an 87 iroc 350 5 speed and the other in an 87 ta in boh cases a performance exhaust was installed all an egr system is is an exhaust gas recirculatio device to burn off any residual fuel mine has been omitted since the swap and i never have gotten a code for it yet.try getting a blockoff plate and take it off your car iit wont hurt the engine!

Pino91Formula

Well Im not the only one fighting with this , well two weeks ago my light came on at a odd time about a mile and a half from my houe , it snever done that,. I chalked up to the fact that i didnt clear the codes from the computer. I have since then done that , and i have had no problems . since i put the $20 special muffler on to test my theory , i will be putting on a new ypipe with catco cats and the slp exhuast system in the next few weeks hopefully it takes care of it , if not im going to have my egr converted to a positive valve system.

PhantomTPI

Bob...

Thanks for the input. Unfortunetly, I do not have a scantool so i cannot find out what my IAC counts are. Nor can i afford a scantool right now...all I've got is that $20-dollar code reader from Walmart. But you have helped me to consider other things as well...thank you for your suggestions. I am going to get my EGR valve and replace it, reset the computer, and see what happens. Hopefully, i wont have a problem after that. Thanks again. Vader-thankx for the pic!
