    P0135 / P0155 Codes

    When that cylinder misfire came on yes, but not since. Revs to go down sometimes at idling after driving for a bit and right before the backfire and loss of power starts. Once I pull off to the side and let it sit for a while it all goes away

    P0135 / P0155 Codes

    Sorry for the late update. Have not had time to mess with the Mustang until today. I don’t have the “Mode 6” on my scanner. Attached are some pictures of the values I got while idling and driving. New code is for misfire on cylinder 3. Checked spark plug and coil plug. Switched it out for...

    P0135 / P0155 Codes

    Tune up was done today. All spark plugs (gapped to specs), Evap Canister, Oil change, new air filter, new belt and checked for any loose fittings. Cleared the codes. After a 5 mile drive, they came back on. Only thing left is the ECU as the mechanic suggested. Anything I need to lookout for when...

    P0135 / P0155 Codes

    Yes, my mechanic is stumped and can’t figure it out. The only thing he can’t point at is the ECU under the engine, next to the fuse box. I changed out the evap canister because that’s the other code and still won’t clear. Mechanic is saying the computer is not registering the O2 seonsors or the...

    P0135 / P0155 Codes

    I’ll ask him to check that. Not too knowledgeable like that. But I change my spark plugs and never gapped myself, my tune up is coming up so maybe it’ll fix something. I figured Motorcraft would be trustworthy lol all these years I’ve gotten their spark plugs and never gapped

    All O₂ Heater + Purge Valve Codes at Once (P0135, P0141, P0155, P0161, P0443) — Fuse/Wiring Issue?

    I’m having the same issue. I’ve recently started getting backfires too, to the point where I gotta pull over and wait it out for a few minutes.

    P0135 / P0155 Codes

    Update - My mechanic believes it’s the computer module by the fuse box in the engine bay. I have started experiencing backfires now, to the point where I need to pull over and wait it out for a few minutes. Mechanic says he has checked for air leaks, all connectors, canister valve and everything...

    Yes, i actually took it to my mechanic that’s always worked on my car to replace them. The Motorcraft ones are currently on and issue persists. Parts were labeled and everything.

    P0135 / P0155 Codes

    I started throwing parts at it, soon as the issue happened. Issues started with original coil packs. I have after market performance ones now. I’ve always used Motorcraft spark plugs. O2 sensors I tried BOSCH & MOTORCRAFT.

    P0135 / P0155 Codes

    Hi everyone, new here. I’ve been dealing with these codes for a few months now and cannot figure it out. Below are the parts already replaced. Recently it’s started to shake a little when idling as if there’s a misfire. Press the gas and it won’t accelerate. If I press it harder I hear a loud...
