Curious to see what you get.
Mine has been on for 2 years now. I did everything that I could and the shop looked at it with no change. I replaced my alternator last year and it went off for about 3 weeks.
Been on ever since. I'm getting Lean Mixture Bank 1 and Bank 2

 

disconnect the battery for about ten minutes and that should clear it, and if it comes back the worry bout it

 

you have a vacuum leak, check your pcv hose.

thats just retarded that you have been driving it like that for two years.

 

its prob a vac leak, but have you changed the plugs and wires or 02 sensor at all

 

why thank you!

As for the plugs, wires, 02.
Everything. The only thing left to replace is the fuel pump. I've thought about it but never gotten around to it.
I work 80 hours a week at my full time job and at least 20 at my 2 part times.
Fixing a truck is the last of my worries.

 

Plugs and wires won't cause a lean code, the computer will compensate for that until it's a misfire. I feel like I say this a whole ton on here about the lean codes being an exhaust leak or a vacuum leak. Also, disconnecting the battery doesn't fix your vehicles, it just delays the inevitable from returning.

 

PVC hose? Where is this at?

What type of exhaust leak, cats bad?
