Is the co trim under the anti tamper plug on the AFM?

Its the base idle under the anti tamper on the inlet manifold/plenum right?

Not sure I should mess wit the AFM as I might feck it

I have swapped my AFM for a good used spare and it hasnt changed anything at all

I believe the answers are yes, yes and why not??

To check CO trim, you need a digital volt meter. Pull back the rubber boot on the AFM plug. Put probes between sensor ground and CO trim then read the voltage, it should be between 1.0v and 1.5v. You'll need to check the colours of the wires but I think sensor ground is the black wire? and CO trim the red with black trace. But you can check with volt meter.

Sensor ground will give continuity to an earth point. The supply will be 12v, CO trim will be a low voltage reading. If you want to find out more, look on the RPI website or do a search on the V8 Forum.
