Hello... I was test driving my 83 Chev RV today.. I drove 50 miles-- Worked perfectly. I topped up the tank, and on the way back, I had a few problems. ...All of a sudden the engine started to miss a bit. ...No backfiring, though. Then it started to surge, as in: speed up, slow down, speed up, slow down. ...It was doing this so much that the RV was going like a bucking bronco. If I stepped on the gas, I'd lose power. The only way it would run smooth, is if I hardly touched the gas pedal at all. If I stopped and reved the engine up, it worked fine. ...Then it would go for a stretch working not too bad.
,,,I won't lie...When I got home, I changed the fuel filter (the little cartridge), and noted that it was quite dirty, and did have some crap in it. ...I am not a mechanic, but does this sound like filter problems, as opposed to being the fuel pump?? ...Of course, tommorrow, I'll try 'er again, but I am concerned that it could be something else, and I'll end up stranded some where. Thanks for any help. ...Jon
