Here is how I tested the harness:
- Disconnected the MAF sensor
- Continuity check between each of the five wires and all the others-ok
- Continuity check between each of the wires and chassis - only one grounded as it should be-ok
- Disconnected the large connector next to X11-4
- Checked all five wires for continuity to the large plug -ok
Anything else to check? I don't want to rip the harness up to visually check the wires. Wiring to injectors & cam magnets new and in good shape. No codes for anything but MAF range.
I tried to twist the MAF connector and see if there was an intermittant problem but that is rather difficult to do and see. When the car stalled I also twisted the wire and connector with no results. When I disconnect the MAF sensor, car starts and runs well.
I'm going to re-install everything tonight and see if the problem is still there. Also going to check fuel pressure and get a new gas cap(127000mi). If the problem persists, I will return the AMM for another one. Does anyone know what OBDI code is set by a defective gas cap?
I am trying to find a wiring harness at a resonable price. I rufuse to pay $1600 for a harness when it should of been replaced at MB expense.
