Ok, now my a/f gauge is fucked up. Once the car is warmed up (o2 sensor warmed up) it will show lean at idle, then, rich at WOT, then nothing on deceleration w/ my foot off the gas. ARGHHHHHHHHHHH! My gauges are so ******* NUTS!! DO NOT BUY NORDSKOG OR CYBERDYNE GAUGES!!!! Oh and 1 quesion, could it because it is the original (100k miles old) 02 sensor?

 

What are you bitching about? Its supposed to do that.

 

Go completly blank when you decelerate? Thanks Felix. I AM a moron!!! I have never seen a digital A/F gauge in a car before (my buddy had a big ol mechanical one in his Formula) so I guess I was not sure what to look for.

 

I would change out the o2 sensor just for ***** and giggles anyways

 

Plan on it next weekend. I can see why it would read differently under idle and WOT, but the thing is, it shows no ratio at all under throttle-less deceleration.

 

A/F gauge is only supposed to b used when ur givin full accelaration, example, if u push the gas to the floor, i lean out, and it goes to RED(lean) but when im daily drivin it, it just stays on lean, so A/F gauge is only used when u push the throttle fully

 

Under decel the car goes full lean, which is off the scale on the A/F guage. It's normal.

 

Rico, how can you have missed the dozens of posts on A/F gauges, telling you the injectors shut off on deccel, causing the A/F gauge to read nothing!
You need “Mega Memory”!

 

Dont know if this helps BUT I did read somewhere that if you O2 sensor has OVER 75,000 Miles on it, IT NEEDS to be replaced! They are easy to replace, even I did one! And they cost very little. Good luck!

 

Bad rico, no rx7 for you.
