Check Engine Light due to code P0171 on Mitsubishi Lancer

The Check Engine Light may illuminate with a stored code P0171. Our technicians tell us this can be a result of an engine vacuum leak at one or more of the fuel injector insulators. Improved insulators are available to correct this concern.
