Same. Any new info?
Sorry to hijack, but my jeep can't get out of its own way on the highway. I nearly have to be in 3rd just to do the speed limit. And significant hill and I'm in 2nd at like 3500-4K rpm to hold 40-45 mph. Jeep has 35's and 4.88's. Auto tranny. 228k miles. Just did a compression test and numbers were good, 125-135 psi. Just recently passed smog with flying colors. Idles fine. EGR working properly. Exhaust is not clogged, no exhaust leaks. Has orange top ford injectors. File pressure regulator is working and psi is correct at idle. Oil pressure is good. No coolant loss. Plugs are good color. Timing chain was replaced a few years ago
Could it just be tired and in need to rebuild? Maybe fuel pump not working when under load?
