Actually, what engine is that?
Here's a 91 4.9L 85 code: 85 The coast down throttle angle offset is more than 5 degrees from the zero value.

this may be related too, a "generic" code 85 on a GM is an undefined gear ratio

68 stepside thanks for the link. the engine is a 454. im thinking it was probably a code related to the knock sensor.. the P.O. told me that the harness by the starter would fall off sometimes and the check engine lite would come on. There was two codes, 14 which was coolant temp which i already fixed, and 85.. i cleared em and so far so good. Still strange though.
