Check Engine Light came on today!!!

I have an Actron CP9180 code reader. I bought it several years ago for under $100. It is great for situations like yours. It will give you the code, you google it and know what you are looking at. I have had simple things like a loose gas cap to big ones when a rodent got to a small wire. On my truck it identified the O2 sensor that was bad. I replaced it for $20. The code reader allows you to clear the codes and check engine light too.

Probably something dumb... The CEL will pop if you leave the gas cap loose, but when cars come herwe with rods hanging out of the block, the CEL had never illuminated.

Post the CEL code to this site and there will be a stampede to see who can get you the correct answer first. Kind if nice actually.

Pretty hard to give any direction without codes. Start with a basic $50 code reader to at least get codes and reset some. It is also good to keep in car in case
