Question about 1999 Chevrolet Silverado 1500
99 chevy truck has just recently been fixed by a mechanic and had the oxygen sensor, head gasket, tune up, now the check engine light is on again and had it scanned. It states running lean on fuel. what does this mean and how can I fix it.
Mine is throwing same code I just cleaned the throttle body with carb cleaner runs much better I just have to get error codes cleared to see if that fixes it if not. Going to try cleaning fuel injectors or replace I am gonna start cheap.

Sounds like a vacuum leak. try spraying carburetor cleaner or starter fluid around vacuum lines and intake while engine is running if you have a leak engine will speed up when cleaner hits leak.
