when driving on a long trip on a hot day the car begins to lose power. car does not show to be overheating, warning light slow down appears, but nothing changes . pull off on a less traveled road and drive slow problem seems to get better.


#2

Which warning light? many parts stores will read stored codes for free, Codes wold be helpful for diagnosis.


#3

A clogged fuel filter could cause this. What year, how many miles, any recent work on the car?


#4

what does your user manual say what to do when the light comes on?


#5

Lancer? Turbo? Maybe there is a boost control scheme to protect the motor in hi stress situations? What model was that? Rally art?
