truck bucks like crazy!! but… not all of the time, at times runs like a champ- have replace oxygen sensors, fuel filter, fuel pump - no resolve- anybody have the solution???

There are only a few hundred things that it could be. What year is this truck? Which engine? Is the check engine light on? Does it sometimes flash? Have you had the codes read?

2002- 6cyl. check engine light has been on but is now off- codes said is was running lean-

light doesn’t flash, have replaced oxygen sensors, fuel pump and filter

Next steps: Check for vacuum leaks and clean the MAF.
