no throttle response? Check TPS?

[joevanni]

yea i think thats what it is cuz the previous owner just told me it has s14 wireharness and ecu but i had a 91 ka24de and i think he changed the throttle body along with the sensor so the wiring harness could match how do i test the tps

i also found that there is a vacuum line in the back of the intake manifold where the egr is located can that cause the problem
