CEL 14 tried to fix

All summer I have been battling with this code = CEL 14. CEL 14 = Idle Control System Malfunction - Defective IAC valve, defective fast idle thermo valve, throttle body. I replaced the IACV and recently checked it to make sure there was no carbon build up. Everyone looks fine with the IACV. Next up....my TPS clip was crack and vibrating bad at high RPMs. It would vibrate the terminals inside the clip loose causing it to throw CEL 14. I got the clip off of a 94 civic lx and ran the wires into it. Then I attached the new TPS clip to the TPS and it created a snug fit. At this point it worked fine for awhile. Once again CEL 14 came on. It does it sometimes when I rev high or when I'm just sitting at a light. I'm thinking of taking off my throttle body and IACV. Then taking some carb cleaner and drenching the TB and IACV down. That should take care of any of the mechanical problems like sticking valves if that is actually the prob. IF that does not work it has to be electrical. Like a grounded wire, bad sensor, or bad connector clip. Guys I have a turbo coming in soon, and I'm scared to death of putting it on until I solve this CEL prob. If you can help me in anyways please do. If you know anyone that can help me send this post by email to them so they can have a chance to post. I'm out of ideas! Please help, thanks!
