I would start with the throttle position sensor and camshaft sensor and then do the other repairs. These issues could cause the the problems you describe.

Agree with F O R. I would clean your throttle body first and foremost. The TPS is integrated into the throttle body, cannot be removed unlike other platforms. You'd need a new throttle body unfortunately. Check the wiring that goes into the throttle body also.
