hi,
i have 1982 300SD 240K miles, that has been converted to run on vegetable oil. I brought the car in to the shop b/c the acceleration was extremely poor, and it was stalling quite often. I've had the timing chain replaced, the intake and exhaust valves cleaned, the diesel tank removed and cleaned, and still the same problem remains. The mechanic is suggesting I rebuild the injector pump, as it may have become clogged or lost its proper functionality. Any thoughts on this? Should i just replace the engine instead? I dont think that the problem is related to the veggie system, as even when those new components were removed, the engine was not running properly (on regular diesel fuel) ... thanks, doug
