Check engine light

I am finding that my check engine light was comming on and I could not figure out why, I have narrowed it down to when I put it into cruise control the check engine light comes on, I drive 30 miles every day so today I left the cruise off and the light did not come on. Anyone know what could be causing this problem. Thanks................drummond

Your check engine light can come on for a variety of reasons. The only way you are going to know why it came on is to have the codes read. Some major auto parts stores will read the codes for free.
