My car idles just fine but as soon as I give it throttle it dies. I'm 99% sure all the vaccum lines are in order but I think the supercharger is not turning on because the led indicator is not turning on and when I unplug the two wire plug from the supercharger the car acts the same. I know it isn't reccomended to give the supercharger direct power but how do you do it so I can see if it really is the problem.
im no expert.. so bump
but in my experience just becasue ur supercharger isnt working isnt a reason for the car dieing when u give it some gas. I think its unrelated, but hopefully someone else here can answer your question in more detail.
A dead SC will not cause the car to stop running when you rev it... sounds like a dodgy AFM experience I once had with mine.
EG... open throttle car revs... dicky AFM thinks engine is still idling... ECU doesnt know to give more fuel/air... car starves on air. Check the resitance outputs from your AFM are within spec with a multimeter. If youer car is MAP sens'd disregard everything I said. Oh yeah that light only indicated that inlet manifold pressure is at or above zero. Usually you gotta be at open throttle for a few seconds for the light to come on. I can make my SC light come on while the SC is disconnected but like fanging up a hill in third gear with full open throttle.
