I tested the air flow sensor pot and I see infinity on each of the pins. When I have everything hooked up and idling I see 4.88v on 1-3 and a range from 0V to 1.3V on 1-2. It swings wildly stays at zero for a second or two then ramps up fast to over a volts then falls dramatically, mirroring the result in the idle - up and down. The higher the voltage the lower the idle.

Can someone please explain? I gather the pot really is dead, no resistance for a start..

Oh great I feel a severe lightening of the wallet... warrgh...
