I am getting 0115 (right bank running lean) and i dont have the money to replace it right now. I will be able to get a o2 sensor at the end of the month.

Do you think i will burn the valves or hurt the engine in anyway for the two weeks?

 

0115 = Fuel injection system lean, right bank.
That doesn't point to an O2 sensor problem. You either have a vacuum leak or a problem with a fuel injector. Don't worry, your not going to burn up your engine in two weeks. If you were boosted, lean, spraying and racing, I'd worry.

 

lean back could be because of many things. O2 sensor maynot fix it.

 

What would be the logical process of elimination.

o2 sensor first, then check fuel injector? hmmm.....
