Check your injectors:

reseat them in the intake manifold.
maybe run some fuel injector cleaner
check fuel filter

you have a leak, or pinched a line, or did something else... you need to find what is broken

Re: Running too Lean

Please post entire code(s). If you're seeing Long Term Fuel Trim - system too lean, I'd look for a) vacuum leak, and then b) test out your MAF.

The MAFs are notorious for this kind of failure.
