Just wondering if anyone knows were the throttle position sensor is located on a 97 z24?

I believe this is my cars problems. When I am at a complete stop the RPM's drop below 500 and the car shuts off it also does it while I am driving, when i step on the gas the RPM gauge jumps up an down then stops it also does the samething after I try to move from a stopping position. Sometimes it acts like it isn't getting enough gas make it move so i am not sure what it could be.

 

The throttle position sensor will be located at the opposite end of the throttle plate shaft, it operates throttle plate in front of throttle body, you can find two Torx screws with it.

 

Thanks. found that now any idea were the crankshaft position sensor is located? I found the camshaft sensor but can't find the crankshaft sensor.

 

On 2.4L 4CYL VIN[T] It's located on front side of cylinder block almost dead center.
