jmurphz33 Posted October 5, 2006 Share Posted October 5, 2006 Hey Z guys; alright, I've had my 280 for a while now, running a stock, FI setup. I'm getting horrible mileage (compared to what it should get), and I analyzed the exhaust gases, with a CO percentage of about 7.2%, and an estimated AFR of 12.8-13.1 at idle. Not good. I've ruled out the ECU, ignition, pressure regulator, both coolant sensors, and switches. I'm down to the AFM. I just purchased a very clean, working one off of ebay. I believe it's a 7 pin, but I'm not totally sure. The clip on the harness is missing two connectors, but I'm not sure if I have a f*d up harness (previous owner was STUPID), or the wrong AFM. Any help would be great! Thanks guys. -John Quote Link to comment Share on other sites More sharing options...
