Mechanic Job in Los Angeles, California

Alternator repair/replacement, air filter replacement, oil change, MAF Sensor check, dent removal. Recently failed smog due to check engine light. Error codes P0170 and P1500 on Mitsubishi Eclipse 98 Gst convertible. Not sure if alternator needs replacement, would need assessment. If needed, require someone who could find me a cheap part - ebay showing $100 for new alternator.
