OK I got the error code out of the ecm and it is 3 flashes, pause, 2 flashes. Which according to the chart I found on the web has something to do with the egr valve. my question to you is, where is the egr valve. also please see my post a couple slots up for more info.
depending on the motor, passenger side of the intake behind the TBI unit is the normal location. it is a big mushroom looking thing, with vacum line's to it. and you are talking about a "32" code. and i belive that code is for "EGR failure" or "EGR vacuum control" this is genaric from memory on GM TBI/TPI ECU code's if you have a crab it is for "barometric or altitude sensor". i would need to know year, engine, and if it is TBI or TPI or carb for fuel system to help more.
