I went back out to the car to watch the eha current at idle. It fluctuates between 0.20mA to 1.69 Ma. If I step on the gas the eha current doesn't increase right away. If I hold step on the gas to really raise the rpms, it hesitates and the eha current drops initially. Then, it starts a very slow rise. As the eha current rises, the rpms will rise and smooth out. For whatever reason, it seems the eha current drops and then slowly rises. Other times, it will rise to 2ma ands then drop to 0.020 mA. The response seems pretty erratic. Not sure what I can check. I'm wondering if the ecu is junk and displaying such odd responses. Anyone with any thoughts is appreciated.
