OK now I'm worried. i'm at 106,000 miles. I don't have any popping noises or anything and I put in MSD wires and NGK plugs around 75,000. Should I do any thing or check anything???

Rearranged the injectors last night, number 7 has a NASTY NASTY brownish buildup on it and gas that came out of that fuel rail shared a similar color and nastiness. The gas bled from the schrader and number 1 injector was clean. Looks like I have some buildup or something in the rail. I cleared the codes and drove around for 20 mins, took a long time for the SES light to come back on. Came on and sure enough Cylinder 7 again.
Any ideas? I think my injectors have def. seen better days.
It is SEMI possible ( I guess 50/50 lol ) that I may of gotten the injectors mixed up and Cyl 7 went back to Cyl 7.
Any ideas on the nasty gunk sitting on top of the injector?

Well I FINALLY resolved this issue. Issue was my fuel injectors, replaced all 8. I also had a vaccum port open right past the tb, by the intake manifold. I plugged this and once the pcm relearned it ran awesome. It is running good now and no CEL. Knock on wood I think I fixed it. What is this port that I plugged?

Thanks man, it definitely feels like an accomplishment.
I honestly think sea foamed caused this problem - thats all I can figure. I guess after 120 thousand miles the stock injectors had seen better days. They looked NASTY.

I had the same code, did the same things you did, and still had the code. I brought it to the dealer to do a leakdown test and turned out to be the rings on #7 were screwed. That was at only 80k.
From what I've read, does anyone else started to think there might be a class action suit building here?

What did you end up doing? What did it cost?
