Spit and Sputter. Service light.
Hey there! Just joined the forum, always good to have somewhere to turn to for opinions. Anyhow, have a 98 sierra Z71 with a 305. Truck has some problems Im tryin to get to the bottom of but this one just came up and is affecting the truck quite a bit. Had the codes pulled and its throwin P0131 twice. Say Im cruisin along and hit the gas to shift down a gear the rpms will drop and shell spit and sputter. This will even accur in neutral. Wont go past round 2500/3000 rpms in neutral. It will eventually get so bad that its nearly impossible to leave a red light until you re fire the truck. Dosnt act up as bad in cold tempatures. Just replaced the fuel filter yesterday in hopes of a solution. Any thoughts?
