Are there any other symptoms, rough idle etc? Could be timing, could be a lot of things.

Has it been converted to MAF?

Code 95 - Fuel Pump Circuit Open-PCM To Motor Ground
Means that at some time you lost power to the pump, because of a bad connection or bad relay.

Ok cause I had to replace relay to turn pump on. So then 95 code is just that then. I took cats off and noticed a little rich. But now it's way too rich. Thinking of swapping out EEC.

Is your engine warming up fully? Mine was running really rich, and my fan clutch was bad so it was spining all the time plus my thermostat is bad so its stuck open, made my car run rich. Getting my stang back for the first time in a month and half since I bought it and its actually running right, now! super psyched
