Hi, I'm Chad. Welcome to JustAnswer. I'm reviewing your question and I will be posting your reply ASAP.
1- have you checked for vacuum leaks ?
2- can you get me fuel trims reading long term & short term at idle ?
3- on the scanner does the Oxygen sensor fluctuate from 0.1 to 0.9 volts at idle , is the sensor working ?
4- what is the fuel status : at idle , open loop status or closed loop status ?
