Check Engine light

Check Engine light is on what kinda things are we talking about that could possibly be wrong with it? "Seems" to drive fine no difference in preformance. It came on after a small persuit i had the other day in my Sonoma 00 i got up to 110 up quick and in a hurry. So any ideas without telling me to take it somewhere cuz i plan too just not till next week.

well first what size engine? and how many times did it flash or did it just come on and stay on.... or has it gone off and came back on?

V6 4.3l and it just came and stayed no flashing

You need to get the codes read. I am willing to bet it misfired

Get the code(s) read. It means that there is an emission related problem which could be many, many, many things.

hmm k so my best bet is just to take it in? Haha ok well thank fellas siea!

Take it to auto zone or a place that scans it for free

I TOOK CARE OF THE PROBLEM! and bought a new truck hahahah!
