G'day Folks,

I'm not sure (but after a replace everything else process of elimination the chance seems to be pretty big) if my air flow sensor potentiometer is causing the uneven idle problems on my M102 or not because I haven't taken the one off of my car just yet...

...But I have "practiced" on some spare parts I bought and I can see on the spare part that there are wear marks in the sensor =>



{ For the record and future searching this is about the following parts
Car Part BOSCH 3437224035, Elements of injection of fuel (3437224035)

Car Part BOSCH 3 437 010 039 (3437010039), Repair Kit, distributor (3437010039)

Car Part BOSCH F 026 T03 021 (F026T03021), Adjusting Potentiometer, idle mixture (F 026 T03 021)

And possibly this MB number 3437224015

These numbers seem to come up in combination with each other - please check for yourself before you use them to buy anything!!!}



Anyway the sensor has skid marks on it where the lever at the end of the "throttle plate" in the CIS air control gubbins have been rubbing up against it...

...I was thinking =>

RE-COAT - repair the surface.

Clear high temperature paint is often used in alternators and starter motors to isolate windings from other parts of the the machinery.

I guess varnish would do the same.

I have the sudden urge to try to repair the surface of this spare part with a bit of yacht varnish.

However before I do that perhaps someone here (perhaps an electrickery genius?) has a better idea?
