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.
I just had to turn the car off, press and hold the trip meter button and start it with it held and wait 10 more seconds and the light went out. If it's really the check-engine light, you may have a problem. These problems range from having the gas cap on loose to a major computer-engine interface problem.
