93 4runner with a 3.0 17,000 miles will run great when first warmed up.Then I can go around a corner,hit a bump and then the truck has no get up and go,or acceleration.Hit another bump and it will run great,then next bump, it will go to crap.All of the grounds are intact.I know I'm looking into pulling the harness down.Anyone had the same issue?
All new TPS,AFM, tune up,Temp sensor,speed sensor.

There is a thread about this around here somewhere. The engine harness rubs through where it crosses up front.

You're in the 84-85 section BTW...
