[QUOTE="93Cobra#2771, post: 9343054, member: 4599"] I'm figuring that the FP was dropped since the injector is so big for the the application. The most that car should have on it is a 24# injector. And C&L plus X3z is a mismatch at best, unless the EEC was swapped to the A9L family. From the description, it actually sounds more like it is running rich than lean. Have you pulled the plugs just to see what they look like? If running rich, they are going to be black and sooty, if lean they are going to be very white with specs of metal on the electrodes. You could even have an issue with a single plug or wire. That plays havoc with the fuel injection, as it tries to compensate for a single cylinder. I had a plug boot get hot enough to crack and cause an occasional misfire on that cylinder. Took me quite a while to track that one down, let me tell you. Intermittant problems are tough to tackle.
