Thanks rock


Hey someone have found good news in in the same boat.. Please let me know i think that is the input and output sensor


Sweet. Just have to know where those sensors are.


Found them on the Tranny. Still no help. Replaced the throttle position sensor and that didn't help. Thinking about just running a cable from the accelerator and making a part for the butterfly that will be spring loaded. My only other option.
