Have you checked your TPS sensor it may need adjustment other possible culprit is the ECT (Coolant sensor) the fact that your idle flutuates suggests the ISCV to be working but it may be as well to remove this and clean with some light oil as these are well known to jamming.

TPS (Throttle Position Sensor) and ECT (Engine Coolant Temperature) TPS is located on throttle body and it's job is to feedback information to the ECU about the position of the butterfly. The signal range is from 0-5V if you search on here there is instructions on how to set these up and a way how to test them.

ECT tells the ECU information about the engine coolant temperature and it then can perform enrichment for cold starts etc.
