All the sudden my car started reading lean today. Completely lean. Here's a video of me on the highway cruisin about 55...video also has a description. From the reading I've done so far it sounds like I could just have a bad 02 sensor..any help would be great. Thanks

still dosent work

 

Where did you install the 02 sensor for this gauge?

 

Not sure, bought the car with it in. I'm catless, if that matters.

 

I'd assume a bad sensor. If it was running 20:1+ your headers would probably be glowing red

 

Sounds like your sensor went bad, very common on those.

 

They have a better chance of glowing red at 14.7:1 then 20:1

 

Wrong

 

Get an egt probe and see what it does at 20:1. I promise you'll learn something.

 

20:1 was just a number. Running lean raises temps in general which increases chance of detonation

 

EGT's are highest at stoich and trend up with less ignition timing and more load. Like I said...learn something.

 

Thanks for the help guys, I'll be trying a new sensor
