SOURCE: sputtering when accelerating

If it idles ok and only "sputters" under load it could be either an ignition or fuel problem. How long has it been since the fuel filter was changed? How about spark plugs and wires? Without the proper diagnostic equipment and the vehicle in front of me, these are the easiest things for the DIYer to tackle with the fuel filter being the cheapest option.

SOURCE: misses during acceleration , rough

Go get the codes ran at auto zone or advance auto parts they will do it for free. If the codes come up as a cylinder miss-fire then it is most likely a coil (being a ford). Write down which cylinder it is. I wouldn't replace any of the spark plugs , useless you have more than 100,000 miles. If you have to replace the spark plugs use BOSH double plautim or better. The cylinder placing is ( as your are looking at the front of the truck) passenger side front to back 1-2-3-4 driving side front to back 5-6-7-8. If you never seen a coil buy one so you know what you are looking for. The coil is held in by a 7mm bolt. Take the bolt out and replace the coil. Problem Solved. Estimated time 20 Mins with 60 dollars per coil.

1998 GMC Sierra random misfires during acceleration


Tune up time. Not pulling enough air, air filter, not pushing enough, catalytic converter. Fuel filter? Could be valves, rings. Do a compression test. Open up the exhaust system first. A bad converter will mess it the compression up. No air in, No air out.

2000 gmc sierra 4.3 eng will start and idle but won't accelerate, it dies when pressing the accelerator.


You need to test the fuel pressure with an accurate gauge. This engine is very pressure sensitive. It has trouble even running if the pressure drops below 55PSI.

2000 gmc sierra 1500 V-8, 4.8liter automatic. oil severely leaking from back of block in between block and flywheel. oil gushes out during acceleration


Between the rear of the block and the transmission is just a couple of things that may be leaking, but make sure thats where it's coming from, and not running from somewhere else...
Your crankshaft rear min seal, they get hardened after yearsm and some can cut a small groove in the end of the crank and leak. They make a "speedi-sleeve" to repair that. The other idea is the camshaft plug, which is like a freeze out plug, but these are not as common.
