[GINOSGTP]

I just installed a stage 3 intercooler kit, 8.8mm wires, 104's drilled 160 t-stat, fuel pump re-wire.....i get all excited about the car and for the past three days a cant get the car to idle!!!! I get p0300(random missfire) as a code! I have tried changing plugs wires checked vacuum lines....I'm out of ideas so can anyone help with this problem?????

bet it is a vacuum leak.

Does it start run for a couple of seconds then die or will it even start and run? could be the fuel pump shutting down.

I thought that the P0300 was a camshaft related issue?
