My car will idie in park but when you put it into drive or reverse and hit the gas it either dies out or after you get going it backfires and acts like it wants to die or sometimes it does die. We put spark plugs wires and a o2 sensor on also 2 coil packs on this car the car has a lot of miles but i just had a new cam and timing gears installed on it i had the garage check the injector and he said it was fine. since we had this car the check engine light has stayed on . if you have any ideas on it please let me know miles is 204000

Check your throttle body position sensor and double check that the timing was done properly. Sounds like something is a bit off.

A 1990 Chevrolet Lumina with 204,000 miles idles in park but dies, backfires, or nearly stalls when shifted into drive or reverse and accelerated. Spark plugs, wires, an oxygen sensor, and two coil packs were replaced, the injector was reported fine, and a new cam and timing gears were installed. The check engine light has remained on. An expert advised checking the throttle position sensor and confirming the timing, and also asked for the engine size.
