Rough idle, but runs great at over 1500 rpm
Hello I'm a new diesel owner and PROUD to be 
Anyway my truck idles Rough, it's a 93 chev 6.2,, it's even rougher like say if I'm sitting at a red light I gotta put it in Nutruel just so it smoothens out. Any suggestions or cures?? I don't have a lot of cash to throw at it too, thanks

Ecg valve? ?
Truck smokes at idle and lots driving off. Not too terribly but she smokes. I did crack every injector line but they all appear ok. Wondering could my ecg valve be the issue?

'93 6.2 model.?. Sounds like a fuel restriction. Check lift pump, fuel strainer, and fuel filter conditions....
