the truck vibrates siting still just reving it, it does it 1st through 6th gear at the same rpms. (1500-1800). feels the same pulling or not

if its an injector problem why would it stop vibrating after 1800 rps? it wouldnt stay the same or get worse?

Well , Are you seeing any smoke , any unusual noise. The vibration could be hundreds of things, Converter or Pressure plate problems , the Damper.... injectors, a dead cylinder. The list continues. Any information regarding the truck and mod's done to the truck will get us closer to a diagnoses!

the only mod is straight piped that i know of i just bought the truck 4-5 months ago. nothing else apears to be moded. it doesnt smoke at all, doesnt seem to lack any power, theres no unnormal noises or sounds, shift smothly, clutch works great. the truck drives just like normal except for between 1500 to 1800 rpms. thats when the hole truck vibrates or shakes. its bad, feels like bad worped rotors when you jam on the brakes, but it does it while siting still reving the engine, driving in all 6 gears, accelerating, and decelerating.
