    '91 Honda CRX Si bought with a "ZC" engine. Ran ok in summer, worse until warm as Michigan temps got cooler. Plugs: dry/black sooty. Seems to be running very rich and dumping fuel (a lot of backfire "popping" at all speeds). Searching for info on engine. Block: ZC6162738 Transmission: L3-2098192. Figured I need details before trying to adjust properly.
