The coronary arteries regulate the supply of blood to your heart muscle depending on how much oxygen your heart needs at the time, as indicated by: 1  The number of times your heart beats per minute (heart rate). 2  Your blood pressure. 3  The force of your heart's contractions.  The thickness of your heart muscle.
When your car's Check Engine light comes on, it's usually accompanied by a sinking feeling in the pit of your stomach. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap.
My car has the Check Engine light come on after 1 minute of the car running, and stay on. It does not flash. No other warning indicators. I have a 1995 Ford Escort LX, 1.9L Auto. I still see 32MPG with it, and cant figure out what is wrong.
