Im having iac valve problems, code 14, I have tried 4 different iac valves, I replaced the throttle body for a skunk2 one, checked the wiring at least 8 times, tested the plug (got power) and I just can't figure out why this code keeps popping up, any ideas on what I should do, what I should get, should I get a new map sensor?, help me out guy's Im trying hard to get tuned tommorow and without that code it will be a lot easier for my tuner to work on it, Im all out of ideas.
