How about bad O2's? Making the PCM think it's running lean so it fattens up the mixture?
How about a fouled plug or 2?
How about a FPR that is leaking due to a hole in the diaphragm?
How about an injector that is leaking due to the fact that it has NEVER been cleaned?
Since you have gotten it running better, did you change the plugs?
Did you even look at the plugs since you got it running better?
