I'm currently using an injector kill.

Yeah. It was only after I launched the message did I see that it was posting to the wrong category.

My '89 Civic has fuel injection. Might you be saying that, with my ignition off, if my manual transmission is still in gear (such as going down hill), that the engine off, compression will still suck fuel into the engine / catalytic?

Thanks for the response, Ecky!
