    replaced fuel pump, regulator, ignition modules, TPS, MAP,Plugs and wires,temp sensor, IAC. Car has a miss 90% of he time. acceleration power is in busts, but the engine smooths out, Some times the chime freaks out for no aperant reason while driving. Some times when accelerating from a stop right around 50 mph it acts like you let let off the throttle, it dont die but wont go. you let off the throttle and back on, its fine. changing ECM next.

    The problem isn't repaired. I found out from a repair bill in 1/10/12 that I possible problems with Engine Module Control (EMC). But I never had it repaired. But now I am having problems with engine going off and back on while driving it.

    I have to warm up my engine before my transmission will run normally. It only takes a minute. That could be the problem with my engine.
