Has any upgrades been done to the car cold air intake ,chip in the ecm etc
Customer: replied 7 years ago.
no,but it does seem to happen at above 3000 feet above sea leval
Expert:  Tom replied 7 years ago.
So it dosent happen at lower levels and it does not actually stall just lose rpms then catches and its fine and no check engine light ever?
Customer: replied 7 years ago.
that is correct
Expert:  Tom replied 7 years ago.
Ok well at the higher altitude the air is thinner and its harder for the motor to breath correctly and the dealer will actually have to update the ecm to adjust the air/fuel ratios so this does not happen make sure when you bring the car in you tell them this only happens at high altitudes they might even have to replace the ecm
