2001 Ford Escort- Rough Idle
Help! I've been having a problem with a rough idle now for awhile. When ever I'm at a red light the car runs really rough, so much so that I'll put it in neutral and it pretty much smooths out. I had the engine replaced in Aug 2013 (used engine) and at times it seems worse now. We replaced the plugs and wires and still rough. If you stand outside the car it sounds great, running smooth, you get in and it's virbrating in park and louder then normal, neutral, not bad, drive,(foot on brake) ROUGH, and the steering wheel vibrating like crazy! Any ideas?? I've taken it back to the shop and they say all the codes check out.
I bought the car in April 2012 with 70k and it ran great! You had to really listen to make sure it was running. In the winter when I turned on the heat it would run rough, everyone said that was normal. After the winter it continued to run a little rough and has progressively gotten worse! Don't know if that has anything to do with it, also April 2013 it was rear ended while parked, put a hole in the bumper but that's it
