I have a scan tool to use ( a friend's) and I need to know what the reading s should be. I am getting a 42 and 44 with an irratic idle. And it shows I'm in open loop. When I started the car it showed closed loop then after a minute or so went to open loop and stayed. Can someone tell me the correct specs on such things as the:

IAC
TPS
MAF
O2 sensor and whatever else you know of that a scan tool shows for an 86 IROC 305TPI.

Thanks,
Tim

 

Is this an Auto Xray?

TPS should be around .54 volts.

I'd check your fuel system pressure (the Auto Xray can't do it for you), since both codes could involve low pressure.
