Code 32 - fix?
I had asked a question regarding a code 32 I received a few weeks ago. I received it after filling up on a warm day and then hitting the highway, which seems to be a common problem. Since I got it twice, both times after filling up, I thought it may have something to do with the fuel cap. I purchased a new cap and did the same routine yesterday with no problems in about the same heat. Just some food for thought - a $7 fix???

I got Code 32 when my intake started leaking. The vaccum around the broken seal caused the trouble code to store on my ECM. I fixed the leak, cleared the codes and haven't seen it since.

Re: Code 32 - fix? (YellowVetteMan)
My 1991 manual says that a code 32 is caused by a disconnect to the EGR valve vacuum. The ECM controls this by way of a solenoid. This is calculated by way of information from coolant temperature, air flow and engine rpm.
The ECM monitors integrator during a Code 32 test and must detect a change to pass the test. Thoroughly check that the EGR vacuum harness is not plugged or restricted. If the vacuum harness is pushed on the solenoid too far, it may plug the end of the vacuum line and cause a Code 32.The vacuum source goes to the orifice side of the EGR solenoid. The EGR vacuum may bleed off slowly, but this is not considered a fault. This valve should close when the engine is cranked over.
Good Luck!

I've replaced everything having to with the EGR on my car and I still get a code 32 on the highway. It started happening right after I installed a better flowing exhaust system (w/ no cats). I'm having a custom chip burned to eliminate the code :yesnod:
