1992 240 Wagon Check Engine Light on, Code 121 AMM and Main Relay. 200

Greetings,
Any Volvo techs every see a problem like this? This 1992 240 Wagon runs great but does stall sometimes, hot or cold. It is fast on the freeway for a 240. It has the check engine light on and the code is 121 which is either the AMM or the Main relay. I tricked the air box a long time ago so it receives cold air 100% of the time, so maybe its a good chance its not the AMM. Has anyone ever replaced a Main relay because of a check engine light and a stalling problem?

Thank You Very Much!
