i've got a pretty annoying problem here... i have a 96 cobra svt (4.6 DOHC). i have no nitrous, no turbo/supercharger. all that i know that was done to my car was the exhaust (i don't know of internal engine work that might have been done before i got it) i picked it up used and drove it around and got on it a few times pretty good. my engine crapped out. i shifted up to 5th one night after a short but intense session (i never red lined it) and it stalled out like it had run out of gas (tank was full). i finally got it to start after pumping the gas and it sounded like it was running off of nowhere near as many cylinders that it has. needless to say i had to keep on the gas to keep it running. my fluid levels were good. my temp gauge didn't read like an overheat. i checked the spark plugs and even replaced them (even though they didn't look bad) i have platinum +4's in it now. and it's running the same way... i was told there were a lot of geniuses on here that could prolly tell me what's up if... if you need more info to give me an opinion ask away, hook me up please... thanks
