Strange Issues

[Guss23]

As I said, we did pull the codes a few times but every time we checked them they were different. I replaced the MAPS sensor, air intake temp sensor, the coolant temp sensor, idle air control, fuel pressure regulator and O2 sensor. Waiting for the chip to return as well as my new ECM. Friday we should know if we are on the right course.

Are you going to install new Pcm and prom at same time or try one at a time to see which does the fix ?

 

[Guss23]

Don't know yet. Probably both at the same time

Try the org. ECM with the new chip first...

So what happened next? I'm reading, reading, reading trying to learn - per Robert Lee's wise instructions - read until you're tired and read some more. Ha!

This a Pontiac and not a Buick; or is it ? You can learn a lot from Turbobuick.com... lots more traffic, lots more info and while they are different the concept is the same.

OK, I'll go over there too. Thanks.
