Ok. Took it to the dealership and the tech and I went through EVERYTHING. Every injector, the entire harness all the way to the ECM, the Boomslang/FIC harness and the ECM.

Found out I had a bad EGR solenoid and a defective/deformed A/C belt in the process. And, that everything checked out perfectly. Sigh. Well, I guess that good in a way. I also swapped the first rev ECM in last weekend and still got the same thing so it's not ECM version specific. I even swaped F/ICs so its not the F/IC, either.

The AEM guys have been really helpful going through this. Got to give them credit for that and their product is working perfectly.

They're getting me a replacement for the 20 pin F/IC harness out so I can swap injector #3 over to injector channel #7 or #8. I don't know how it can be but it looks like there's something wonky with injector driver #3 in the F/IC. Can't figure out what it could be that would only affect just the '97. There are a couple other Sports running F/ICs without any issues and tons of Eclipse, etc. guys running the F/IC 6 and F/IC 8. Weird.

I have a spare 20 pin harness - and my 1-BAR GM MAP came in - so I'll rewire #3 over to a spare driver and see what happens this weekend.

I am going to swap back to the 5.38 gears next week. The 4.90s are just not working out. <img src="/forums/images/graemlins/frown.gif" alt="" /> The 4.90s dump it into Open Loop WAY too often and its really affecting mileage. Three extended highway climbs and the altitude at the new house is just killing me.
