I just bought this car, and it ran badly. When I checked the codes, it only had Camshaft Position Sensors Bank 1 and 2. So, I replaced them and cleared the codes out. It was running pretty good. Then I went and unplugged the Throttle Position sensor and cleaned the connection and opened up the butterfly valve and cleaned behind the Throttle plate. Once I did that is when I got the code P0507 Idle Speed control system-RPM too high. And when I start it up the rpms do go up to 2,000. My question is, if I unplug and/or clean in front of and behind the Throttle body plate on this car do I need to do an idle Air control volume relearn for the ECM to be able to get the right reading from the TPS? If so, what is the correct relearn process and the steps?
