Problem between injector and PCM!!
Problem between injector and PCM!!!!! My car started trembling about 2 weeks ago, so I took it to the dealer to see what's up.
Find out that 2-4 spark plugs are shot. Fixed, then the #8 cylinder is shot. The tech tells me it might be the injector, so they replace it and it is still not running the way it should. Then they tell me it's not the injector, that it has to with my PCM. He told me that tere is some kind of misfire communication problem with injector and the PCM. Now if it is the PCM, do I send it back to ED Wright to reprogram it. THe tech said that their scanners couldn't tell what was wrong due to all of the modifications that I have had done to the PCM. <img src="images/icons/mad.gif" border="0">

Re: Problem between injector and PCM!!!!! You didn't give a lot of info on your car. What year it is how many miles, did you get it used etc...How long have you been running the H/C setup? Your injectors could be shot... They won't take going static forever and if someone before you ran dry N2O or if you've had the H/C for a while on stock injectors they could be worn out. Get bigger new injectors and a better fuel pump and you oughtta be OK.

I bought the car new. It's a 99 T/A with 37000 miles. I've had this setup for about for about 6 months now. The tech told me the injectors were fine. All except the #8 cylinder,so they replace it and it's still doing the same thing. Now the tech down here seems O.K. I mean he's the only one that works on LS1's. Their scanners aren't telling me ****. They say I've deleted alot of the codes outa my PCM. They just tell me that it's still misfiring. Now it's drivable but I gotta know for sure before I drive it 4 hours to Houston(MTI) to get any thing replaced or send off my PCM to ED WRIGHT to see if he can fix the communication problem if it is the PCM.
