My 2004 GMC has 72,000 miles with no problems except the injectors. the first time at 42,000 truck had bad smokes, dealer said need injectors, record indicates they changes 8 injectors, work was done in less than three hours, ( do you beleive in that). Then again over time black smoke again. at 72,000 took it back, comments needs 8 injectors. so they changed it took couple days with rebuilt ones. No more black smoke. I never had power issue or other problems except oil gets dark early, ? diesle fuel and oil pressure reading is lower, at hot idle # 25-26.( it was 30).
The question I have, how long more I can trust this sets of injectors. The car is going out of warranty in November10. Is it worth of keeping, and swallow 4-5 thousands dollor repair cost in near future or just sell it and forget about diesel any more. Thanks
