Afm Problem?

[b1ancardi]

Hey, I have a series 1 RB25det, with the green label AFM, and the car was running rough and rich, and I just bought a second hand green label AFM, connected it, disconnected the battery for 20 minutes (to reset the ecu???), re-connected the battery, and started the car.

It runs smooth, but still rich? If theres heaps of fuel in the system still, could it just be that it hasnt all been burnt through yet?

Sorry to hijack your thread bud,but I too have this problem, its idling fine but blowing black fuel smoke, its running hell rich... Does any know if this is AFM related?

probably your o2 sensors

pull it out (may need a big ish spanner cos mine was in way too tight)

ppl have reported that theirs have been covered in so much soot that the sensor could not get a reading

so once you have it out give it a spray with some carby cleaner (black shit will come out) and give it a shake, if it rattles then its f**ked but if nothing, chuck it back in and see how you go

or for peace of mind replace it anyway

if the car is driving fine but running rich as and using heaps of fuel then its the o2 sensor
