i just recently installed oil pressure and air/fuel guages, and i was just wondering what kinda pressure you guys were running, and where your air fuel is at when your wide open? thanks

I'm not sure if it's all the same. I have an A/F meter by AutoMeter. When your at WOT it should read "Rich" or Green. Anything less you should be concern!

When your driving, constant speed, or cruising speed the light should bounce back and forth from Red to Green. This is normal because the O2 sensor is constantly adjusting and trying to read the air mixture.

There is more indepth explanation why this happens with the instruction of my A/F meter that I don't remember.

At idle my car is reading just above "stoich" (first bar of green). Now I was told that the only thing that an A/F is good for when reading is when your at WOT and it better be running rich or green. I have not verified this yet but it does make sense that you would want your car running rich at WOT.

at idle, I'm around 12psi once fully warmed up. At 300o rpm, I'm at 50 psi, at 5000 and above, 75psi.
