I was stopped at a red light, and out of nowhere the engine starts running extremely rough. I put it into park, and it calmed down. Ever since then, every time it is in drive, and I come to a stop, I have to put it in neutral so it wont shake. That is very common with motor mounts. I replaced all 3. Same issue. Then finally a check engine light came on, and the code read evap purge valve failure. I replaced that. Same issue, except then the a/c stopped for about 20 minutes. It's in the shop now and they replaced 2 other temperature sensors, and say it might need a new transmission. Worst vehicle I have ever owned. Also have replaced the battery, alternator, door lock actuators, both rear calipers, both rear electronic parking brakes.
