Did you ever find out what was wrong.. mine is doing this on a regular basis about once a week.. they reset computer in car but still doing itFirst really cold day today in ohio..I started up my 2.0 that was parked in garage and boy was my idle so rough car was literally shaking....calmed down after about 15 seconds or so....anyone else experience?
Ya mine is the push button start up.. i went higher grade gas to see is this helps.. but I really shouldn't have to be buying better gas..lolIt happened to me twice in hot Florida. I noticed it's a bug in the ignition. If you just tap the starter instead of a full twist of the key something goes out of time and it seems like the car is running on less than 4 cylinders. Try to be more aware when turning the key.
