93 3.0 SR5 4runner- developed stutter at 45mph but goes away a lil past 50 mph. TPS sensor maybe? Truck has about 1 year old NGK plugs and wires and newer cap and rotor

 

Does the vibration/shake happen at that speed despite the gear your in, ie 4 or 5th etc...

Rear drive shaft U-Joints? Take off your drive shaft and feel how the u-joint move.

I'll look into the U-Joints...its its almost like the truck is trying to stall when it happens. Around 45mph while you are still accelerating there is usually 3 or 4 good bucks. till about 50mph. if you let off in the 45-50 mph range it stops, but as soon as you get back on the gas it starts again. i believe it happens in 4th or 5th

 

Does the engine run up to higher RPM's in the lower gears?

Fuel filter, fuel pump/pressure/flow?

Good luck, Luc

 

Thanks Luc! great link for sure!

 

Well figured it out. Clutch is shot...after driving for hour and half last night it was starting to slip. Truck has a little over 130k and it is the stock clutch i believe.

Thanks again for the help!
