I think I may have an injector driver that is acting up.

Are there eight of these in the pcm? What kind of scan could tell me if one of them is malfunctioning?

The problem is intermittent and will cause the engine to run rough about every other time I drive it.

I had a bad PCM ground for a while and I think it caused something in the PCM to ruin itself. I was busy changing all kinds of other things that I thought could be wrong with the car and finally checked the PCM ground and it was REALLY corroded.

Does anyone have any experience with this sort of problem?

 

Yes, the injector drivers are in the PCM. Try another PCM and see if the problem goes away. If it does, just replace the PCM.

 

OK.

How much for a loaner PCM with the option to buy it?
