as i said before, it is probably one of those simple little things that are being overlooked. it might have been simple but it had a lot of us stumped. the car was in an accident last week and as soon as i can i will look for this simple piece even though i didn't see it when i removed the intake but then again i didn't even know to look for it. thanks for the info.Thumbs Up

The switch is on the 85-89, but not on the 90-91.
A different ECM in combo with a solenoid took care of it.
Solenoid is under the TB on the driver side on 90-91.
Not sure if 85-89 has a solenoid and/or in the same place.

the solenoid is mounted on the thermostat housing. i got an upgraded one for it as the original did the same thing. i also know they have the solenoid on an 88 as blackvette88 is a friend of mine. thanks for the info.

Question about the Code 32.
 
Those who have trouble shot the EGR system after a code 32, have they also checked into the charcoal canister as that is also connected to the vacuum circuit?
 
I have code 32 popping up now and then, but don´t want to dig into that one, but maybe it is where the culprit lies for many of us.

never really thought of that but it does make sense. car is in body shop and getting stripped down for repainting. will check it after i get car back. thanks for the tip.
