Mitsubishi Lancer Check Engine Light due to code P0171

(5 reports)

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.

P0171 replaced MAF, CKECKED FUEL SYSTEM, RESET ECU, STARTS but will not RUN -
