Hello, I just purchased my 1999 Chevy Suburban 4x4 K1500 5.7L in October of 2010. I've been slowly working through issues with it and have one last issue with the fuel consumption. It seems as if the truck consumes more fuel at idle (I can see the gas hand move if it idles - just setting, not driving, long) than while driving at freeway (70mph) speeds. Truck lacks acceleration during passing maneuvers. It doesn't buck and***** like it did when I got the distribur wet, just slow acceleration from 60 or 70 mph. Also, when I stop and park the truck I smell gas fumes, but there are no leaks externally. Could my spider system be leaking down when I park the truck? Would a pressure test show me this? Also, would replacing the fuel filter have any effect on this?
have the same problem?
