Needing any suggestions

Asked by GuruZH9YR Nov 05, 2017 at 12:56 AM about the 2003 Ford Focus ZTW Wagon

Question type: Maintenance & Repair

I have a 2003 ford focus and it's misfiring or
something every time im sitting at a red light it's
like it's jumping or shaking even when it's in park
but doesn't do it as bad. I've checked shark plugs
and wires and put a knew fuel filter on it. Any
suggestions on what may be causing my problem

Do you have any codes being set? If so check them. You can also clean the throttle body and especially the MAF sensor. Just be sure to use a MAF sensor cleaner only, as something like carb cleaner can destroy it, you'll see bottles labeled MAF cleaner in any parts shop. After cleaning everything check in and around coils for any cracks. An injector could also be causing a misfire or rough idle, you can try your luck with an injector-cleaning additive in your gas tank, or you can check injectors with a noid light.
