Try your original PROM just to test your theory.

Or give me a call and I'll come visit. I'm off this week (gone next week). I have an interview on Wed. at 2pm but before or after that I'm free. Let me know if you want any help. I think you have my phone number in a previous e-mail I sent you. BTW: I fixed my car, got it running REAL good, it was the timing. Somehow the distrib walked (don't know how) and so I just retarded it a little. Now the car starts right up and idle is back to normal. THANK YOU Judd Porter!

Brian, do you think you might want to work on it either Thursday, Friday, or over the weekend? I will be free and plan on coming up some time, Might be thursday night.

I am disapointed to hear that the module wasn't the problem, but you know it was going bad anyways from the testing! SO after its running its just one less thing to worry about.

I agree with the above post to try your old PROM and see if it runs. I am sure it wont be smooth and I would definately say the computer will not like that LT4 cam, though if it runs better you know its the Chip. What you need to do is get JPrevost down and see if hes got a custom chip in his, if so just switch ECMs. Like what Chris Payton did with my Escort to find out if his ECM was bad. Then if it runs well its the ECM.

Another thought it to try cleaning the COntacts with some electrical spray. IF that doesn't help call fastchip and see what they say about the problem.
I would have called you to check you progress, but I have been soooooo busy with Finals that I cant wait to have them over with tomorrow!
