I have a 98 f-150 that was misfiring on 1, 2, then 3 cylinders. Last week I was given a second f-150 with a blown transmission but it runs just fine. So i took the coil packs and plug wires off of it and bought new plugs. I just installed them all yesterday, now it sounds ok at idle but once I put it in gear it idles really low and I have less power than a 4banger unless I put the pedal to the ground.
Ideas? The truck has been sitting for the past month so I was pretty pumped to have it running... I just want it running well now!!
check engine light just came on, haven't been home yet to hook it up and see what the issue is, but it's not flashing so not a misfire right?
I'll run down to autozone and get some water remover this afternoon.. I don't think the gas is bad. I put the gas in there abot a month ago when it first started misfiring. Can gas go bad that quickly?
OK
so i'm thinking that the coils might not have been my problem?
Check engine light started flashing today, hooked it up and I've got a o2 sensor code and misfire on 2 and 5.
I may have read it wrong, did you replace the spark plug wires too? Reading it sounds like you did the coil packs and spark plugs and used the same old wires.
