1994 GT misfire problems.
Hopefully someone can help me out with this,
I have 94 Mustang GT and here recently its been having issues with misfiring. I noticed a slight misfire so i changed my plugs and wires. now when it idles, the mis firing became worse. so figuring that maybe it was a bad wire i switched back over to the old wires. now it "vibrates" all the time and its driving me insane!!! can someone help me out??
