I just bought a 1996 Cobra Convertible and am already having problems. When i start it up it will load up and sometimes will die, but after i rev it up it clears up and runs awsome. Also, sometimes when it dies, it doesnt want to start up. The ENTIRE fuel system has been replaced within the last 1k miles. What could be the problems? The car is completly stock except for the SLT cold air. It had a 90mm mass air on it when i bought it and replaced it with the stock one. Any help?
