kslb Posted August 20, 2019 Share Posted August 20, 2019 Good evening, the gauge for my AEM AFR stays on 14.8 I am assuming I just need to remove the sensor and give it a clean but thought I would check on here first. It runs round the dial on start up as expected and fluctuates a little then sticks on 14.8. The car runs fine and the wiring seems good but before I get the lemon juice out I thought it was worth checking if anyone else had a similar issue. Car has been in storage for a while as well. Many thanks. Quote Link to comment Share on other sites More sharing options...
tayr Posted August 20, 2019 Share Posted August 20, 2019 Do you have an X series? I believe it needs to be calibrated from time to time Iirc (could be really wrong) you have to unplug it and run it not plugged in to the exhaust and run the setting on the gauge Quote Link to comment Share on other sites More sharing options...
kslb Posted August 20, 2019 Author Share Posted August 20, 2019 I will have a look into that, not sure what model it is. Never had to calibrate before but it has been in storage for years. I will give it a clean up and see where we are at. Thanks. Quote Link to comment Share on other sites More sharing options...
kslb Posted August 21, 2019 Author Share Posted August 21, 2019 Cleaned the sensor with lemon juice and now all working as it should. Didn’t look that bad but all sorted. Quote Link to comment Share on other sites More sharing options...
