So, title says it, I have a CEL came on this morning. I think it's because it's damp and wet outside...got a lumpy rough run at tickover, but if I hold gas pedal down a tiny bit, it goes away...seems like a misfire caused by wet leads or similar.

Anyway, I want an OBDII reader, and I was looking at THIS one from crappytire. Will it do what I want, and enable me to do correct troubleshooting and trouble avoidance?

Your input is appreciated.
