thanks for the feedback guys!! I've checked the fuel pressure and looked for vaccum leaks but with no luck. I took the car to a mechanic friend and weve been trying to figure it out a little. we've found that its definitely an electrical issue. the alternator wasnt charging the battery at all and that was because of a fryed fuse link. we fixed that but now its pumping out 16-18v which is really not good. the external voltage regulator is brand new. we even hooked up another new one and nothing changed.
so my problem is: The car is overcharging at around 18v. But its something other than the alternator or the voltage regulator.
