It is impossible to check the resistance of a MAP sensor
This is because it is a semiconductor device not a resistive one.
Have to say, most of this sounds like a classic map sensor fault to me
mmm very strange, i have a fault finding map from Ford and they describe that you can measure the resistance of the MAP sensor, it must be between 50 and 600 ohm's. (Cosworth fault finding)
@ Wimwerf, i just called a local Ford dealer and they didn't know anything about 071's so i called a big Ford dealer and they knew it
so i got the 071 plugs but no difference.
Tommorow i'm gonna change the MAP sensor, and i hope that the problem is gone then.
