I! Have a late model 02 ford focus, . It idles slow sometimes stalls at a stop but while driving revs up real fast. Any suggestions? I need help bad [email protected] is my email address. Thank you in advance
If you have a Zetec engine, then one thing to check is the PCV hose at the rear. It is often mushy, torn, and/or collapsed at the 90 degree bend where it attaches just under the throttle body. BTW, hard to see from topside.
