I am at my wits end. We recently bought a 1998 4.0 v8 and have had all manner of problems. After a head re-build, brain un-lock new plugs and leads (the firing of which has been proven) I am left with a misfire and loud popping of air when pressing the accelerator. This results in a severe lack of power and the rangie stalling.
Could this be an air fuel mixture problem? If so does anyone have any idea how I can resolve this?
Really don't want to give up just yet.
