After heads/intake isntall on 99 Firehawk, car has a miss at idle/low speed Installed 224 cam, absolute speed 2x heads, ls6 intake, underdrive pulley, slp headers (o2 sims), hardened pushrods, etc.
when you first fire the car up it runs smooth and quiet, after about 2 miles of driving you can feel the miss in the car (almost like it has a huge cam) and when accelerating from a stop you can really feel the miss.
Plugs, plugwires, injector wires all look good. I dont see anything not hooked up. Its been missing since the heads/cam install.

Re: After heads/intake isntall on 99 Firehawk, car has a miss at idle/low speed what pulley did you use, i have heard of pulleys causing a miss. i believe it was an slp pulley that caused the miss on jfm's car, but his miss was up top at around 5500 rpm. he switched to an ASP pulley and it went away.
