when i do like any speed in a gear were its at a constant speed the truck like cuts out of feels like your giving it gas and letting off and doing that again.

im thinking it could be something to do with the throttle body so this weekend im gonna try it since i have one layign around


help would be appreciated

 

by the way its a 90 4x4 3.0 v6

 

My truck was doin the smae thing i cleaned the throttlebodt and it helped try seafoam

 

i change out throttle bodies and it runs great

i think the tps was bad

 

Perhaps it's time to pull the ECU codes and see what the problem is before wasting time and money.
