Hi everyone. Im sure this has been answered dozens of times. Its Sunday and Im stressed.
New to diesel world. Very knowledgable with gas jeeps.
Unsure of a lot of the abreviations so spell it out for me please.
2004 6.0L stock configuration, 140,000miles
No power top end, won't go over 50 empty or with a minimal towing load. Lots of Black smoke. Trouble with hot restarts and 4.5 miles per gallon. No CEL codes. I have a scanner but it finds nothing. Why won't it throw codes its ovbiously broken?
Whats the difference between Check engine light and wrench light. I thought wrench light was a joke laughed like crazy. Now im not sure.
Pulled EGR valve, mild fouling, cleaned and reinstalled. Slightly goey but have no reference for OK vs bad oil cooler/EGR cooler.
Pulled Map sensor, broke off nipple, cleaned hose(seemed clear) bought new sensor and replaced, no change. Going to check all CAC? boots. Im guessing those are the rubber collars on the aluminum pipes?
Can I test the VGT valve? Any ideas or point me to links to learn abbreviations and diagnostics.
