BluDestiny Posted August 1, 2012 Share Posted August 1, 2012 From recently messing with my afm, I can tell you that the afm uses an air temperature sensor right before the flap. Mine basically has less resistance then needed and now the car runs rich and can't rev past 2500 rpm. I would take the afm out and test the air temp sensor. I can upload a picture of what pins you need to test and what resistances you need. Quote Link to comment Share on other sites More sharing options...
