I have a 1989 Toyota pickup with a 22re just under 200k miles. The truck will idle great and sounds perfect revving it stationary. Once I’m driving and it warmed up (after about ten min) the truck starts bucking when any throttle is applied. It’s almost like I have traction control where it cuts power. I have replaced these part
-spark plugs
-plug wires
-cap&rotor
-coil
-fuel filter

I also tested the fuel pressure and I was at 44psi at idle and about 39 when revved up. If anyone has any ideas about what it could be please feel free to say some thing.
thanks, will
