ok i have a 94 4runner sr5 v6 5sp and when i accelerate or go up a hill the rig slightly studders almost like when you shift gears when the rpm's are too low but more subtle. so i am wondering if there was air in the clutch fluid would that cause the problem or maybe the oil leaking from my rear main seal may be causing slippage or if it is an ignition problem. also it looses speed when i go up a hill, even if it is a low grade. please help

 

um i would check your spark plugs and wires, your wires could be sparking. also i would run some seafoam or other injector cleaner and go from there

 

yea mine does that to. Mines a auto 4speed and mine does it when I decelerate. Like when I accelerate and then just let off it does that to.
