check engine soon light

When my Silverado stops at a drive thru, the check engine soon  light illuminates. After driving awhile, the light goes out. I have changed the spark plugs and wires.

Re: check engine soon light

You need to put a scanner on the truck to see what trouble code is stored in the computer memory. If you don't have the access to a scanner you can take your truck to your local AutoZone parts store and they should be able to scan the computer to tell you what trouble code is stored in the computer memory and tell you the problem area. Or you can take it to your local automotive professional and have them scan the truck for you.

This is the only way to find out why your check engine soon light is going on.
