7.4 petrol P3 cold running problems
I have been asked to go and look at a chevy motor-home it is a 7.4 petrol p3 engine i am told.
The description of the fault is ........ starts and runs but clouds of black smoke out of exhaust this continues even when warm and runs rough at temperature, it is as if it has a choke sticking and is constantly pumping fuel in ?
any ideas were to start or a possible cause ?
