I am real bummed out :-(
I got some great help from folks her on the TRS forum in my on going Saga. As most know I have issues of popping / Missing. My truck runs great at first start up let warm up 5 min. I get on the freeway its an uphill climb from 3200ft to 4000ft in elevation. I get like 4 miles up the grade it slows from 65mph to 45 mph than starts popping missing. I pull over waite until cool runs perfect again if not it will still pop and misfire it has to cool off first
I changed the TFI to new Motorcraft one and put new spark plug wires on with new plugs. I did see corrosion on three terminals and rust in the plug wire ends I cleaned each one than installed the new wires. I did notice the coil terminal was loose I could turn it by hand on the cap. I replaced TFI and wires and plugs not the coil. I fired it up runs perfect at 800rpm's at idle no jumping no jerking real smooth. I feel good thinking its going to run great well same area of the highway same area of the hill it starts loosing power popping missing. I got home running crappy shut it off replaced the coil fired up runs perfect it was only 10 min. Test drive 65mph than same area same issue over and over
My main thought is WTF why? I got to town popping missing opened the hood I could hear like a sharp sound like its miss firing between cylinders running on 5 cylinders. If the Dist cap and rotor was bad it would be miss firing from the get go not where I am having issues. I can't afford a used Toyota Tocoma off Road 4X4 at 20K I need this 4X4 its rough in the winter here. I am just lost spent almost $200 still in the same issue it can't be that hard to figure out
Any ideas or help is very much appreciate
