I have preformed the wiring harness replacement that was desperately needed and have replaced the throttle actuator with some improvement to my problems. But the main symptoms persist listed below. Check engine light on.

Flash codes: LED gives 2, 3, 17, then repeats. Cruise Control inoperative.

Problem: while key is in "ON" position, not started, throttle actuator clicks violently and erratically, also a rapid "relay click" is noticible inside cabin in passenger side dash near kick panel. The relay click inside is also constantly clicking while driving. The idle is high, around 1000-1100. During HARD acceleration the car has a hesitation, sometimes jerking. Please, someone have a holy grail answer for me?
