ok, so my 4.0 still isnt happy. it chuggs and is very sluggish from idle to 2700 rpm. once it his 27K it comes to life.

i have a CEL that comes and gos. it has thrown code 177 and 176. it comes and gos. i have not found any vacume leaks. if i run a tank of high gread fuel and injector cleaner its clears up till that tank is gone.....

i have replced the following

air filter
fuel filter
plugs
plug wires
coil pack
