somethings going on with my daily driver. when i'm driving in the lower gears 1 st 2nd and 3rd i get a jerky feeling in the low rpm's. it's almost like the truck wants to die on me. then as it gets up to about 3000 rpm's it runs fine. until i shift again, then it jerks until i get up to 3000 rpm's. i'm not sure what the problem is. i had my fuel injectors cleaned last time it was in the shop. i thought maybe the clutch was going bad or something. any info would be great because i would like to fix the problem myself.
