hi everyone, i have this problem my truck has no power when in gear, but when its at idle i can rev the motor and rpms come up fast like its got balls then when im driving its gut less. im not sure what it could be.........stumped........ by the way its lifted, geared, 3.0 5 speed.

 

first off..lets see some pics of your rig..just because..lol

second..could it be clutch related???..maybe your clutch is like..burned..

 

timing too far advanced?

 

what gears/tires?
