Okay.. my truck has been doing this a while now.. but SOMETIMES when i get on it.. and hit 4500rpm or so (sometimes 5) my truck misses? or acts like the rev limiter is right there.. I just replaced plugs.. and fuel filter. I'm thinking its coil pack or MAF.
Has anyone else had this issue.. here is a video.
listen to 1st gear.. and again in 3rd.
