I know i asked this once before, but i have some new information that someone may be able to recognize as a symptom of.......
The glowplug light will not come on when the temp drops below 65 or so. Period. Once the engine is up to normal operating temp and you start it up right away(running into convienence mart etc..), the glowplug light works fine(big help then!) I can still start the car, but when it is cold i MUST pump the accelerator, and then it fires, however missing badly, the misses clear up in about 2-3 seconds. When i start it this way i also notice an absurd amount of smoke coming out the exhaust and it's really quite embarrassing(especially in front of two fine girls who just complemented you on your mercedes!!!) When the plug light did work most the time(about a week ago) the car fired right up no problems at all, and smoked VERY little. It seems to me that if it were a glowplug itself that the light would be out all the time, and not work when the car is warmed up or it is warm out. Sometimes the light doesn't even come on when it is warm out, but it isn't a problem then, and that only happens about 1 out of 20 starts(when it's above 70 or so). ANy thoughts on this? could a bad plug really cause this even though it's intermitent?? One more question, the car is a 83 300SD, i was wondering how long it should take the car to get to normal operating temp when it's 60 degrees outside, it takes it about 10 minutes right now. Thanks
