Mileage141,594Service Date4/21/2025Services Performed- Technician performed multipoint visual inspection, checked Oil, Fluids, Belts, Battery, Charging System, Tires, Brakes , A/C, and Heating System. Our technician inspected and scanned the vehicle system, and noted the engine idling rough , test came back with codes : MISFIRE(P03031 cylinder # 3, and P0171 system too lean, and therefor; he recommends to replace all spark plugs, 1 ignition coil (preferably all 4 but customer declined), air mass flow sensor(MAS), and the vehicle is due for an oil change as well, plus throttle body cleaning. The customer approved the job recommendation, and the technician ordered the parts, removed and replaced one ignition coil and spark plugs, changed oil and filter, air filters are clean and OK. The technician then scanned the vehicle again, both codes went away but engine was still idling rough, checked and performed a FUEL PRESSURE TEST, it was below( 35 to 38) normal specification of 44 to 50, recommended to replace FUEL PUMP, and the customer approved it plus the technician mentioned that the MAS was not needed, therefor; gave credit back to the customer. After the work was done, test drove the vehicle, the fuel pump replacement made a big difference and rough idle went away but code P0171 was still evident. At this point, The technician smoked the vehicle system, a leak was prominent from the fuel tank CAP, replaced it with an oem one, cleaned up the MAS, recommended to replace Oxygen sensor as well , cleared the code, test drove the vehicle, its running fine now, no check engine light, and per customer's request took the vehicle to our neighbor for an SMOG TEST, it passed the test, and issued a certificate # UM563048C.
