-- Select a Model -- 98 Ford Escort, Misfire Problem AGAIN

-- Select a Model --

Alright, so I posted before about a problem that was thought to be a bad fuel injector. Heres the update. The car started misfiring on cylinder one a few weeks ago. Started as a sputter from getting bad gas. Ran some lucas injector cleaner, and some dry gas through it, replaced the fuel filter. Still sputtering. The sputter turned into a severe hesitation and jumping. At first, it only did it on occasion, and evened itself out quickly, but progressively happened more often. Usually only happens when the car warms up but sometimes does it when cold too. Does it while it idles, and at all speeds. Flashing SES light says cylinder one misfire. New spark plugs, plug wires and a fuel injection cleaning service later, it stopped for a day or two. Came back full bore. Mechanic ran full diagnostics, checked the plugs and wires AGAIN, still nothing. Checked the fuel pump as well, still nothing. The injector on cylinder one developed a ticking sound, and buzzed sometimes. Mechanic said possibly a bad fuel injector. Had that replaced yesterday. Problem is back full bore. Huge hesitation, loud stutter, injector ticking again, and misfire code is back. Any ideas whatsoever here? I've got three different mechanics stumped on this one.
