Fuel Sys Too Lean - Check Engine Light On
 

I took my 2006 Accent to the workshop in order to get a diagnostic from a CHECK ENGINE LIGHT. Scanner showed Fuel System Too Lean problem. Mechanic asked me to replacement Canister and Pressure sensor. I am not sure if that will solve completely the issue. Does anyone have a idea on issue root cause and how to fix it? I appreciate it. Thanks

have you replaced your air filter with a K&N or the intake with a cold air system? if not, first thing id check for is a vaccuum leak somewhere in the intake system
