Got an AE82 twin cam 4age, that runs off tune . Had my mechanic try to fix it but problem always comes back. After a dyno tune it runs fine for a day then gradually starts stalling from low idle, missing and cutting out with engine light comming on over bumps, and out of the blue. At cruising speed the car becomes jittery with the car jerking like there isn't enough fuel getting into the engine. My mechanic cleaned the injectors changed fuel filter, checked and cleaned sensors and connections, dyno tuned it, and came to the conclusion the computer is stuffed, saying its memory is stuffed. Just want to know if anyone else has experienced the same problem, and whether the computer is really the problem. Please help
