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.

Sohc or dohc (exp model)?

You said:
"New spark plugs, plug wires and a fuel injection cleaning service later, it stopped for a day or two"

We can move parts to see if the mis fire changes cyls.
Swap wires for cyls 1 & 2. Swap plugs for cyls 1 & 4, Swap injectors for cyls 1 and 3. If the mis fire moves, you have narrowed it down.

Was the coil checked?

Try a compression test on Cyl one when it's hot.

Yes, forgot to mention, the wires were moved, nothing there. Not sure about the injectors though. Will try that though. Same thing with the coil, and compression test. Hoping all this doesn't cost an arm and a leg, seems this vehicle is hard to narrow down problems on. Thanks.

You need to find a competent shop and stick with them. If your paying someone then they should have better answers. Jumping around to differents shops just drags out the pain and expense. When someones starts working on it, they start at the basics, the next guy starts there also.

Actually, I've been working with my father in law, who is a retired mechanic. And also, I started out by going to one shop, the guy didn't have much of a clue about anything, so I'm now with another guy, who ran all the diagnostics and tests and so on. The car is going back in tomorrow to have the wires and injectors moved, and if nothing comes up, a compression test. The coil was checked, and was good.

Well, if it was me taking my car in, I would tell him to diagnose it. IF you go in and tell him how you want it diagnosed, the responsibilty falls back to you. My point is he is getting paid to fix it. LEt him bear the responsibility.

Problem being, I already went that route with two mechanics, the first one coming up with nothing at all. The guy I'm going to now at least found that there was a problem, it just has everyone pretty much stumped at this point. I called him back today and he wanted to do a compression test anyways, so it's going in tomorrow, and I let him know what else was suggested as well. He is bound and determined to get to the bottom of it. He already knows that if I'm paying him, something had better be done. I won't pay for anything thats absurd or not nessecary at this point. I'm confident that he was at least in part, accurate with replacing the fuel injector, because the buzzing has went away, but yet the misfire returned. I really believe it sounds like something electrical myself, seeings how the longer the vehicle runs and warms up, the worse it gets most of the time, but diagnostics were ran twice and nothing comes up. Thanks for the advice
