Well i got my car running good after the new cam and headers and such and it has been running trouble free for a couple days. All of the sudden the car is shaking more, runs aweful, almost liek one cylender isnt firing. I pulled a couple plugs and they are black with carbon. What do i do????

 

Try your old coil once, maybe the MSD went bad. Another thing that can foul plugs fast is FP problems, I have heard of the regulator leaking internally and sucking fuel through the vacuum hose, do a little digging there.

 

i scanned the car, one of the 02s was stuck at 4 mV, so i fixed that its it purrs liek a kitten. WEll, a kitten wiht a cam in it
