Misfire
Well I'm back again, ok 98 F150, 4.6, 138,000 miles, started misfiring this morning pretty bad CEL flashing, checked when I got to work showed misfire on 1, when I got home I checked all of them to make sure they hadn't worked their way loose,(had that problem with #8) all were tight, so I turn the CEL off and drove it same thing only worse, this time it was showing #1 and #8,change the wires a few months ago, any ideas on what is going on now? Thanks

I had a similar issue with another truck--an Isuzu Rodeo with a miss on #3. I changed the #3 plug and coil, but no help. Then replaced the #3 injector which required replacing the intake manifold gaskets. That fixed it. If you've got compression and ignition, it could be mixture. Maybe head gasket leak sucking coolant and causing misfire?
