check engine light is on
Hi there
I have a 2007 Chevy equinox, every time I accelerate on the highway and reach 75
mi/hr engine light come on and when I go down hill its start flashing then stop when
driving on level roads. A licensed mechanic check the car and he said you have a miss
fire codes but he is thinking the EGR is the problem. this problem began 18 months
ago and I still driving the car with no other problems. the only thing bather me about
this problem is that the remote starter does not work until the check engine light off
and this happen after one or two days when its came on, but if I keep driving the car
on highway with speed over 60 mi/hr, then the light will stay on. need an explanation
please. thank you.
