I am writing this for a friend who is having problems with his '94 RR Classic LWB with a 4.2L.
While driving along, randomly, and apparently somewhat often, he will get a smell of gas fumes in the cabin, then the truck will start running rough, hesitating, losing power, sometimes completely dying. He will pull over, wait a few minutes, then start it up and it will run like nothing ever happened.
Sounds like something in the fuel issue to me, but not sure what specifically it could be. Any ideas?
Thanks in advance,
