I recently re aquired my 95 Cobra for the second time. The car was tuned at a NMRA meet and the tuner burned a Revolution Diablo chip for the mods. Anyway I went to install the chip and did everything as instructed but with the chip installed the car fires as soon as you turn the key but then idles like a .800 cam and will run barely but dies. Throttle response it great but it will not run. Any suggestions?
