Here is a noob question, when checking for the voltage on the TPS, does the harness need to be connected to the sensor? TPS = Throttle Position Sensor, for those that did not know.
I suspect one of the following has gone bad:
TPS
ECU
Spark Plugs
Vacuum Leak
The ECU is a year old.
The Plugs are 2 years old.
TPS is original.
I'm getting a jerking acceleration when I'm driving, so I figured I would start here.
