replaced coil packs and plugs, still misfiring?
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!!
