2004 Ranger XLT 3.0 (not flex) 5 speed 2wd
Truck runs great when cold but as it warms up, it becomes sluggish and loses all low end power once up to temp. Taking off it bogs down heavily but hasn't stalled. It will rev up but still seems to be way down on power. It will throw a misfire code when under load, codes vary from random to misfire upon startup to cyl 6/2/3/5 (not all at once)
Parts that I've changed; plugs, wires, coil, sensors (crank, cam, maf, ect, iac, tps, o2), cam synchro, two injectors, fuel pump and filter, both heads (reman) and thermostat.
I've changed plugs twice, from NGK to Motorcraft both gapped to .44.
Thermostat I've changed twice, first one was factory temp current one is 180deg.
Cam Sync I've triple checked position multiple times using TDC.
All three cats are gutted.
I'm not sure where to go from here....
