I have replaced egnition module coil pack,cam sensor,crank shaft sensor,and last Ithe throttle position sensor. It misses bad when im driving and even misses when it idels and reving. Idk what it could be. The engine will stay.on for months at a time then suddenly go off and the car will run great. No misses or anything. Then it will come back on if u go to to pass someone and it will flash a gew.times then start running like crap again. Can u help me or no....
