Previous Repairs, and the short story
The vehicle was delivered to us after talks about the original issue with the vehicle, which was poor performance and fuel trims high +45.
During the Conversation about the vehicle it was decided that a new air flow meter be installed and the vehicle test driven to confirm the fuel trims are coming back into line (+ or – 6%)
The vehicle was fitted with a new aftermarket air flow meter and fuel trims checked on the test drive.
