Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello, how many miles are on this vehicle?
Slot of times misfiring at idle but clearing up off idle can be one or more wore out spark plugs. Do you have a way to know what cylinders are misfiring?
If you are referring to the vacuum line on top of the EGR valve it will only have vacuum when the valve is opened. The amount of vacuum varies based on how open the valve should be.
As for the ABS that is a different concern to the engine misfiring. Due the the rules I am supposed to only answer one question. The ABS is considered a different question and I can get in trouble to answering it. A generic answer is you have a bad brake light switch based of what you told me though.
I believe they want you to pay per question. If you get a membership and somehow it is cheaper. Since I work independently from justanswer. I'm not sure exactly how it works. Is your ABS light on? If they performed the abs test and the brake pedal wasn't pressed but was supposed to be you will get this code. Do the brake lights work? If the brake lights work and the ABS light isn't on there isn't an issue. Since the abs is a primary safety system it will pick up faults almost instantly.
