This is what I know from hooking up my scan tool (at idle):
1) Both Pre-Cat O2 Sensors fluctuate up and down.
2) Both Post Cat O2 Sensors steady around 0.735
3) MAF reading 3.5-4.0 g/s
4) Pulled Oil Fill Cap, and idle became very bad and there definitely was vacuum present.
The MAF spec above says 13-15 kg/min, should that be kg/hr?
If I do the conversion it is in the ball park 12.6 - 14.4 kg/hr.
Still have not put in the Techron.
