I just had my service engine light come on, and was told by the local autozone that it sent a code of P0507 and "The PCM has determined that the engine RPM is higher than expected for the current operating conditions". Came on this morning when first started. Also came up with P1580 "Electronic throttle monitor PCM override".

Any ideas? Has anyone seen this?

Car seems to be running fine, but I think I may have noticed it idling just slightly higher than normal when in park and warm. Where should it idle once warmed up?

Thanks!
