Ken I am with you it sounds like a Map issue or possibly a slightly out of sync Stepper motor /TPS, I would be running the "Adjust ISCV" in TuneECU, if the stepper/TPS sync is not set right it will cause idle issues, I recently cured a mates idle problem by checking and finding it out by only .02 volts, it was .14 difference instead of .12
