I have a 1997 grand marquis. And it just started running like its misfiring. It shutters when I accelerate. Help please mad plugs wires o2 censors.????????? I'm confused
Plug in a scanner, or have an auto store do it. With the codes, it's easier to track down the problem, it will even tell you which plug, if that's it. Could be lots of things. Clean the MAF sensor also, just in case.
