just bought a 2002 24 valve 4x4 and love it but when i took a long trip the excellerator acts up drive along at below 6o and try and excell it does nothing till you really push acellerator almost all the way act diff in o/d but still not right seems to rpm hop around also all of this below 60 mph

 

Do you have an automatic transmission? Sounds like the transmission is slipping. How many miles on the truck?

 

yea its auto 170 thousand miles do you thinks it just torque converter or some thing deeper in ?? when you push the acellerator down far enough it does drop down a gear or out of O /D if you take it out of O/D it acts pretty normal between 50 and 60 mph , even if trans was bad wouldnt engine rpms go up as you push accellerator because when you drop below 60 mph and push acellerator rpms dont increase untill it drops a gear or out of O/D towed a boat and 1 ton of rock over 100 miles yesterday aqnd it acts same with load or with out . helpppppp !!!!!!!!!

 

jumping rpms sounds like a torque converter lockup issues

 

could it be a throttle possition sensor seems to have a lot of peddle travel with no change in rpm between 50 and 60 mph
