06 Couple Questions.

[I candy]

I don't know anything about the s197. I may buy this one tho. I already saw it once but didn't make the deal when i found out it was salvage AND the check engine light is on and low beams don't work. The seller didn't know it was salvage either. Now we know its salvage i did some research on value. Power seat wasn't working forward and back till i kept messing with it. But I still can't come up with an offer unless i check these issues out.

In a couple hours I"m going to go back and pull codes to get a better idea.

my question is... Is there any reason why both low beams may have burned out at the same time?

Also do you need to upgrade the computer if there is a CAI. Also what code would pop up if it wasn't tuned?

By your command:

A code P0420 may mean that one or more of the following has happened:
• Leaded fuel was used where unleaded was called for
• A damaged or failed oxygen sensor (HO2S)
• Downstream oxygen sensor (HO2S) wiring damaged or connected improperly
• The engine coolant temperature sensor is not working properly
• Damaged or leaking exhaust manifold / catalytic converter / muffler / exhaust pipe
• Retarded spark timing
• The oxygen sensors in front and behind the converter are reporting too similar of readings
• Leaking fuel injector or high fuel pressure
• Cylinder misfire
• Oil contamination
