[QUOTE="DC97Cobra, post: 8868616, member: 40424"] I went around this block last year and thought it was the COPS. I reinstalled the originals and the car ran fine. Keep in mind, this happened right after I filled up my gas tank over at a local Cheveron. Ironically, I went back to that same Cheveron and the same problem came back. I finally did some diagnostics and watched the pressure to the left and right bank of injectors. The pressure seemed fine until WOT. The pressure would increase and then start to stumble when i reached over 3500RPMs. It looked like steps on the graph through 1st and 2nd gear. I would smooth out in 3rd gear but could still see the steps in the fuel pressure. This, however, has been going on for at least 10 tank fills. If it was water, I would think that it would have gone away by now. I'm now thinking fuel filter, fuel pump, or maybe the fuel pressure regulator? [/QUOTE]
