HELP 2001 gmc sierra will randomly start misfiring
My truck is a 2001 gmc sierra 1500 4.8L 4x4 with 196k on it and lately it started to randomly start misfiring so bad i cant go over 45 mph. This started to happen after hydro locking it in a mud hole. Ive replaced the MAF and that didnt do anything. I dont want to spend a lot of money on replacing more random parts so if anyone has any ideas it would help A LOT. THANKS!
