Some scanners like the rented ones will still read it for more information such as fuel trim an each bank an its especially ideal when another person is monitoring it as your driving it an 02 is heated up .

I love the obd2 / Elm327 bluetooth ,that sends it to your phone on free app.[ many versions].an records ,tells you when readiness monitor is on ,etc . Ideal when another person monitors 02 short term/ long term lean an rich bank readings- as you drive it.

Of coarse theres the 3 key CEL check too .. but little information..

Again--do you have a exhaust leak?
BIG FACTOR TO 02 READINGS!

 

Hello and thank you all for the info,and no I have no exhaust leaks nor vacuum, I got frustrated and ended up taking it to a shop, so will see if I'm gonna have to wash cars for them or they inherit a dskota,cuz it's gonna be expensive I'm sure.

 

Hello all ok well I guess the shop said it's a manifold leaking getting fuel backed into the system,idk I kinda blacked when I heard the price,anyway I just wanted to thank all fir the help,I definitely learned some things .
