My car Idles rough when I have it in gear, idles even worse when the A/C is on. It would even make the car turn off if I turned the A/C to the highest setting. It no longer turns off just shakes and idles rough. The car also accelerates on its own with the A/C on, like the idle will gradually pick up speed. So far I have changed the MAP, sensor, PCV valve, spark plugs, filter. I have also cleaned the throttle body with the CRC brand cleaner. I wasn't sure on moving the blade manually as it is electronic and i read you shouldn't. My car doesn't seem to open the blade while having the key into the ignition on position while having the accelerator pressed though. I also don't know if I am supposed to do the relearn process. I have tried leaving the battery unplugged over night but I still have the rough idle. I have noticed that the A/C Clutch is stuck engaged all the time and does not disengage. I have tried spinning it by hand as well and it doesn't move. My A/C is still cold. Could this cause the engine to idle rough though and the surge with the ac on? Any suggestions or help would be greatly appreciated.
