I have been chasing a pre-ignition problem for two years now, HELP!!!! I have a 95gt that is a total pig. When the car is cold or it is winter the car runs great but when it warms up outside the car loses a ton of power and picks up a horrible pre-ignition. the only mods to the engine itself are adj fpr, pulleys, and exhaust. The timing is set at 10 degrees and the fuel pressure is set at 35lbs. We have messed with both extensively and no gain. this is our first time messing with the 95 and all the foxes I have had never gave me a lick of trouble. The plugs are stock heat range and we have varied that as well. is there any problems with cu, sensors, tps, or anything that is specific to the 94-95 that i am not aware of. I would greatly appreciate any help I can get!!!!
