Check for a vacuum leak somewhere. By the by...you can google any code you have and it will find all kinds of info on the code your getting. Give it a shot.

here is an exact description of that code i found... Lack of Upstream Heated Oxygen Sensor Switch - Sensor
Indicates Lean - Bank No. 1

Seems most of the posts I found on it say to check for vacuum leak.

first place I would check for the leak and is vacuum boot on the lower intake at the back of the engine. Cant see it but if you can fit you arm back there you will be able to feel it:tu:
