dkorinko Posted December 17, 2003 Report Share Posted December 17, 2003 Ok not a huge deal but just something i have started to notice, i have an air to fuel ratio gauge on my car and i have been noticing it is going way to lean. Like when i hit the gas a little bit while driving it is fine, it goes into rich and then balances back out but when i stomp on it is goes into the red (lean) and stays there....whats going on??? Anyway to fix it???? Quote Link to comment Share on other sites More sharing options...
4PASNU Posted December 24, 2003 Report Share Posted December 24, 2003 How long has it been since you changed your fuel filter? Quote Link to comment Share on other sites More sharing options...
god910 Posted December 24, 2003 Report Share Posted December 24, 2003 Our cars have no idea how rich or how lean they are. They can only sense stoich (14.7:1) so when it goes lean they add fuel, when it goes rich they take fuel out. Idle your gauge should just sit there and go back N forth.

4PASNU Posted December 24, 2003 Report Share Posted December 24, 2003 Isn't that how it works with all cars? I thought that the computers in cars where constantly adjusting A/F and that is why A/F gauges bounce back and forth like that. From my understanding it's only when you hit a certain throttle position that the A/F ratio will lock into a setting. That is when your A/F gauge should display somewhere in the stoich area. If you are getting a lean condition at WOT then there is a problem. Quote Link to comment Share on other sites More sharing options...
dkorinko Posted December 24, 2003 Author Report Share Posted December 24, 2003 Changed the fuel filter and changed the chip, ( I have many for the car) when the ignition is set to the on position the air to fuel reads "ideal" and then as soon as i start it, the gauge wont even read??? Im confused??? :x Quote Link to comment Share on other sites More sharing options...
