Over the last month I have had idle and misfire problems, car shakes really bad. Threw 0305, i replaced the coil and dealer replaced the fuel injector, said its fine now. 2 weeks later it starts again, throws 0300 and 0302, local shop cleans throttle body, replaces #2 coil, and new plugs.

Now the shaking is back again, I was sitting in traffic with the AC on for a while, stopped to get gas, started up and the shaking starts, does it for 5 minutes and the idle returns to normal. Later that day I drove again, was running good, turned on the AC for a few minutes and stopped to get food, start up and it starts shaking again. This time as it is shaking I turn the AC back on for 30 sec and turn it off and the shaking goes away.

I am really confused here and dont want to throw more money at it hoping its a sensor. It is not throwing codes now but the shaking is not normal, Ive had the car 5yrs and its never done this before.

Anyone else experience this? I feel like it has to be related to the fans or ac compressor, but not sure.
