Been working on the erratic idle issue for a couple of weeks doing the following:
1) BHR ignition (was going to do this anyway)
2) New MAF
3) New E-Shaft sensor
4) Clean throttle body
Idles pretty good now (was fluctuating between 500-1300 RPM) around 820RPM.
One of the issues that was brought up as a possible cause was the upstream oxygen sensor. I put on an ODBii reader and got the following:
Mazda RX-8 Oxygen Sensor values
Doesn't look right to me as I should be seeing an upstream B1S1 and a downstream B1S2 value. Not sure what this means since the car is idling 100%
better with the above work. Anyone know what's going on?
