I've got a miss at or about 3200 rpm. Doesn't matter if it's sitting in neutral revving or going down the road. It runs good up to that point with maybe a little miss just every once in a while. If you run it on past the miss to say 4000 rpm, it clears up and smooths out. Compression checked good, fuel pressure checks good. It's got new wires, plugs, cap and rotor button, new TFI module, new injectors and new MAP sensor. None of it has made a difference.
It was this way when I bought it, though I thought the miss was nearer to 2500 rpm at that time. I'm guessing it's probably the ECM, but according to the paperwork I got with it, that was changed previous to my purchase. Possibly the wrong one???
Any ideas from the group?
