As stated in the title, I've noticed that the car has either a missfire or stutter issue. I have no clue what else it could be. Things I have already done to the car, due to the milage and maintenance, I have replaced the coil pack, spark plug wires, spark plugs, put in new valve lifters and push rods, new catalytic converter, new exhaust manifolds, new mufflers, replaced the fuel filter, put in a cold air intake... i think thats it. The car is a 2000 3.8L with about 155,000 miles on it. It idles fine, and when I rev it it rev's fine. But when I put it in gear and hold the brake down and then rev it to about 1300rpm it revs up fine for about 3 seconds and then starts to sputter BAD! It doesn't kill the engine, but the whole car shakes bad! I'm at a loss of what else could cause this. I've put so much money into the car already and can't figure it out.
PLEASE HELP!!!
Thanks!
