Hey guys, I'm getting a check engine light that randomly lights up. It only turns on when driving, and never at initial startup. Today, I checked the code and found a code 17. My car is a 1987 Accord LXi (5 speed). If you guys could tell me what code 17 is, it would be greatly appreciated. Thanks.

Thank you very much.. It's weird, the light comes on randomly, and sometimes does not come on. I also noticed that my tach is not working properly, the need bounces up and down. Could this also be linked to the check engine light? Thanks a lot bro..
