      I posted the problem of misfire #3 and misfire during first 1000 RPM's plus I posted A/C problems. Problems finally solved!!!! I replaced alot of parts, but did not find a fix. Plugs,wires,coil pack,crank sensor, o2 sensors, fuel injectors and intake gaskets. Than my ac started acting up! Cold at idle than it would warm up at highway speed. Replaced the compressor. Had it professionaly serviced! That did NOT fix it either. I took it to the dealer!!!

      They found a wire going to the coil pack that had pushed back in the connector that was not making connection! They replaced that connector with a new one. It had been arching across long enough it also fried my new coil pack too, So they replaced it too. Misfire problems solved!!! It also fixed my A/C problem, The ECU (engine computer) sensed the rough, misfire problem and it would automaticly cut the power going to the A/C compressor.

      So all my work and $$$ was fixed for $272 dollars and a visit to the dealer. Hope this helps someone else. Thanks
