think about how the meter works it uses a voltage to measure the resistance by reference
so if the car has a bad earth the meter is being effected buy the introduced voltage by the car feeding back through the high resistace joints
Thats sounding better bud. Im not good at assessing values, but to me, the change in what ive found is way too high, and personally im begining to think that this has been effecting how my lexia works, and making it play up. I know that pin4 goes to a main earth cable, prior to screwing to the body, and pin 5 goes straight there. This is reminding me of the TPS earthing being effected by the MAF lol. :-)
