OK, do you have a digital volt meter?

tap into teh O2 sensor wire and run it to the cabin, you can watch the O2 voltage as you are driving.

you are right - .5v is middle, <0.5 is lean, >0.5 is rich

it should swing from rich to lean at idle, and go full rich at WOT.

check it out.

what sort of injectors are they? 2-3ohms or 10-12ohms?

I can't seem to find the wire from the O2 sensor. That goes into the ECU. One book says it is the white wire D14. But there is no white wire at D14. The other book says it is a orange/Blue wire C18. But that wire gives me a constent 13V.
Which wire is it?
