The car is a 98 svt with 93,000 on it.
Well the issue is that I have been having a stumbling in my car? I took it to ford and they said cylinder 3 plug was shot. It turns out that the store had given me two APP 765's instead of APP 764, so I replaced with the tight ones. It got better and then it went back to the way it was. I took all the plugs out and regapped them and it got better but then back to the way it was.
So the other night I was driving through downtown ATL and I got on it full throttle and I looked in my sideview mirror for some reason and I saw a nice cloud of black smoke (fuel). I think that I had a similar problem a couple of years ago, and it turned out to be a bad injector so I replaced them with green tops (yes they fit with minor work). I do not have any CEL's so that is why I am assuming fuel because spark usually would set of a CEL. Any help would be much appreciated.
My next procedure was going to be the pressurized fuel injector cleaner and berryman's on the UMI/LIM.
