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.
