Put iridium spark plugs in it and a set of ac plug wires...got my wires off e-bay they are $80 and up elsewhere. my 99 gmc sierra smokes all 4 tires now, but had the same symptoms before. this is maintenence anyway no loss either way. this will definately rule out the plugs n wires at the very least. dont assume a big problem b4 ya got one.

Try the Mass Air flow sensor, I had the same problem. I cleaned my MAS and it has been working great since.

Check the fuel pressure regulator. Mine was doing the same thing and the pressure regulator was the problem.

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.

Could be some internal carb problems. Especially if the carb is original, or if it is a rebuilt off the shelf. The internal parts can get old and stop working, such as the accelerator pump.

Check TPS for smooth and linear electrical response over the entire range of motion. If the response is jumpy or erratic at all, replace TPS.

From red light truck started sputtering and and stalled out


Hello. The GMC Sierra has an electric fuel pump so you should ensure that its fuses and relays are working before checking it. You may need to clean your fuel pump or replace it if your gas tank is not empty, but your vehicle has difficulty getting fuel. The GMC Sierra comes in a variety of styles and trim levels that can affect the replacement fuel pump you choose.

It could be one of your sensors, take it to an auto parts store and have them plug into the computer to get a print out of the problem....you also should check your converter, may be plugged. Good luck.
