I've been working on my friends 90 gt for the past 2 days and i can't figure out what is wrong with it.It has a miss in it and it doesn't idle or run right.Ok so far we have changed the plugs,wires,cap,rotor bypassed the msd tried a different coil,tried a different mass air checked all the vacumn linesand still nothing also checked the timing.Does anybody have any ideas? could a map sensor cause this?control module?pickup coil?we need sugestions and we can't dump tons of money into parts he doesn't need.Also there is a hiss in the fuel line couls it be a bad regulator it does run rich.THANKS
