I just need to know what the ECU looks at to adjust fuel ratios. I am going to check my cooling temp sesor today and wiring. Is there anything else I should look at?

I never have left it that rich. I always adjust my AFC to the max lean it can go can I idle around 13.6-13.9. Before a warm start I can adjust my AFC to run lean as i want or rich as i want. After warm start Im ony limited to how rich i can run. I do notice a slight loss of power when driving...

Thank you for letting me know that Nick M. Im wondering if I can ask you something else? Is it normal for the car to run RICH as hell at idle/cruise after a WARM start? When I get into my cold car my ratios are 14.7 at cruise/idle, AS SOON AS i turn off the car and start it immediatly, the...

I thought I would try another O2 sensor but it does nothing. If I leave the O2 sensor disconnected the car does the exact same thing. It shows no codes for O2 sensor and it runs exactly the same (rich only after you turn the key off then back on again) If I unplug my afc and start the car...

Sorry if I come across as a dick. I'm understanding more and more each post I read and make. I am just going to follow the flow chart for diagnosing the O2 sensor and see what happens. Thanks for your help.

My aem gauge says air/fuel ratio written on the box and on the gauge itself. I do not understand what you mean Jetrock. Let me just give you this example to show you why it doesn't make sense. If I leave my AFC dial on, let's just say 3 to make it easier to explain, and drive my car in the...

Alright I'm going to explain my problem in more detail. It seams to only happen after cars warm and a key cycle. I can get into my car on a cold start and drive it as far as I want for as long as I want and my air/fuel ratio is perfect. As soon as I turn off the car and start it again, I'm...

Sorry for being a noob. Like I said I'm trying to figure this out. i guess I'll try something tonight then.

I have an 87 7mgte supra. The previous owner installed an old school AFC with the single knob. He had an exhaust gas temp gauge but I recently installed a wideband something I understand a little better. Now I'm having a weird intermittent problem with my fuel ratios. Sometimes it runs 14.7 at...

hello all, I have an 87t with an apexi AFC and an apexi AVC-r boost controller. I am a total noob to this stuff, Ive tried googling it but I can only find the "SAFC" which has multiple knobs, mine only has one single knob. I also have an apexi AVC-r which is beyond confusing, i dont know...

Im no wiring expert but I checked my wires/connectors on the CPS and coil pack. everything looks good. everythings connected and plugged in. Can someone tell me the location of some grounds for these? i have had a bunch of problems with bad grounds (starter relay, brake lights etc) so it might...

Car is my daily driver. Drove all day yesterday fine, to work and back and out all night. Left my buddys house started fine, go to his stop sign car just shut off.. started her up ran fine, just gave it a little half throttle shot and doesnt even get to 3 grand and car like lags or cuts off and...
