my 2005 ford escape has an idle issue when in drive, and sitting at a stop light. the rpm will flucuate enough to cause head lights to dim. problem is not as bad when in park
Start with the basics. When were the spark plugs changed? Ford recommends at 100K. Check Engine Light on? If so scan of codes. If not, clean the throttle body and IAC of carbon. Might try and clean the MAF as well with MAF cleaner. How is your air filter? Check for vacuum leaks.
