Just got done putting a set of trick flow TW heads and the stage 1 cam. I also put on some 24# injectors with a recalibrated 75mm pro-m. Now the car wont stay running. It will start but dies almost immediatly its almost impossible to keep it running even when I keep giving it gas. Timing is set pretty close and checked for vacuum leaks. Fuel pressure is set at 39 with vacuum hose off. If I unplug the mass air meter it will actually stay running and is even drives pretty close to normally. Does this mean that the mass air is bad? When I do attempt to drive the car with the mass air plugged in it is so horribly underpowered that the car will barely move. I know that the 94 computers are extremely picky, but I figured it would at least run decently. Thanks in advance for any help.

go over all your vacuum lines again. then check your timing again. then, unhook your battery for about 10-15 minutes. the problems with out OBDs is that even though your problem is fixed, the computer is still searching. i had a massive vacuum leak and even though i fixed it, the comp memorized it and kept acting crappy. quick pop off of both terminals and we are set.
