I have some small problems on my 87 Camaro.
It is a 305 engine that has been converted to TPI.

The car starts and runs fine. Idles normal at cold starts and everything looks good. But I have some problems with the SES light. It is glowing all the time and I tried to ground the terminal to check codes. I got code 32 and 34.

Yesterday my SES light was not glowing when I drove the car, but then the car acted a little bit weird. When cruising in low speeds like 30mph the RPM is very unstable..It is lying on 1300RPM and jumps a little...Hard to explain..

Any idea of what this could be??...
I have been looking on a code chart to check the codes and there it stands that 32 is EGR problem and 34 is MAF problem...

Any ideas??...Also the when engine is varm and driving slow speeds. The car is about to stall many times. When brakes are on and the Gear is in Drive the car is stalling very often...What could this be?..TPS and IAC is adjusted...

 

The EGR code is often the temp switch not working (tells the ECM that the EGR did actually open when commanded). The MAF code is often a bad burn-off relay (up by the PB booster).

 

Ok..I guess it can be the temp switch since it was a used switch from a old TPI setup....I can also test the EGR solenoid and check it...I use the same EGR solenoid that was on my carbed engine because I had this computer controlled quadrajet carb and they also have the EGR solenoid...Is there any difference on the TPI and carbed EGR solenoids?

Is there any way I could test the MAF burnout relay?..or do I just have to buy a new one to check it???
