Q: Q: Engine light won't go off

asked by on

I've replaced a coil pack, both O2 sensors, both solenoids to canister, spark plugs, wires, gas cap, air filter & a faulty throttle connector on top of the engine. Have disconnected battery & manually cleared w/ scanner. I drive less than 50 miles and light comes back on! Have done this three times. What else do I need to look at? How many times does the memory store the codes?

My car has 159399 miles.
My car has an automatic transmission.
