1999 GMC Yukon
I have a 1999 gmc yukon 5.7 litre v8 4wd with 108,000 miles on it. it has been running like a champ until just recently. i noticed that the idle was running low while in park, and then it sputters a few times, as i put it in drive and press the gas at a normal take off, the engine sputters and shuts off. ive recently cleaned the MAF, replaced the air filter, new fuel filter and spark plugs and wires, and until now no problems. i rechecked everything to make sure there were no vacuum problems and there werent, the air intake is fine and the throttle body is clean and in good shape, and the fuel pump is operational and sounds strong, also it starts up fine, and no black smoke leaves the exhaust, but water seems to be dripping out, and the funny thing is there is no check engine light on. Now, as i give it gas directly from the throttle body, it revs perfect with no problems, but when i go inside the truck and actually hit the gas pedal to rev the engine, it sputters and stalls, and it wont rev past 2000 rpms even with the pedal all the way down, and it also back fires with a popping noise out of the air filter box, i also notice that the crank fuse has no power going to it, could this be the problem? or does the problem seem more like a MAF problem? and one last thing, the engine will gradualy get up to speed, but if i mash the gas it shuts down almost completly. im confuzed and am not sure what too look at, at this point. please help!
