    oh boy been a while since ive heard a pre obd code but code 32 is an egr problem. First thing to do it apply vacume to the egr and and the engine should run fairly rough and want to almost stall. If it does ur ports in the intake are clean if no change or little change you will need to clean out that port.Just the first basic test could also be the exhaust pressure problem causing a flow problem or also a vacuum problem either a vacuum solenoid or vacuum line to the solenoid or the valve.. Give it a quick check and post what you find and go from there.

    If you dont have a vacume pump u can just lift up on the diaphram of the egr with ur finger. It wont tell you if the diaphram holds vacuum but it ck if you have restricted intake port. still could have restriced exhaust port.

    Sounds good, its not a complicated system we should be able to figure it out.
