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?
