Hi Bill,
Thanks for the detailed instructions. I assume then the O2 sensor is working its an SG36 Standard Motors 3 wire only 9 months old. The values do change but no matter how much we try we can't get the value to go below 8.55.
Before this whole thing started I remember the idle air screw was half way in and lead 22 read 7.6V
Now, the idle air screw is almost all the way out. I tested the AFM according to the book and it seemed like it passed.
Bad primer fuel pump replaced, main fuel pump and filter replaced, leaking Fuel Pressure Regulator replaced, bad Aux Air Device replaced, O2 sensor replaced, Tachymetric relay replaced, bad NTC engine coolant sensor replaced.
I haven't tested the Throttle Position Sensor yet. Engine runs very well now but is still running too rich. Any other tips?
Cheers,
GS
