I've had a bad idle problem lately and just used a noid light last night to figure out one injector is wide open (Brightly lit) all the time even key on engine off. Anyways, I suppose its a computer problem, but which one do I need to change? Under dash? Under hood? I don't know. Any help or part numbers or someone got one for sale would be much appreciated.

Welcome to the forums.

When I had a similar experience about 11 months ago, I had the Powertrain Control Module (PCM) replaced. It's located on the RH side of the car, and you can access it by removing the RH side trim cowl inside the passenger seating area.

Here's instructions from the 1994 Service Manual:



Good luck to you!

Thanks for the diagram and your help! One more question, looking on car-part.com and there are like 10 different kinds, i.e.-F4WF-AC, F4WF-AD, F4WF-AE, etc... Do I need to match mine to one of those? Thanks again for all your help. Adam
