volvo error 121,144

I have a 93 volvo that has the "check engine" light on. The error codes are 121, and 144. Does anyone know where I can find information on how to fix or information on exactly what the error codes mean? Your quick response is greatly appreciated!

Try your luck on the appropriate forum at www.swedespeed.com, www.brickboard.com, or www.vvspy.com.

Good luck.
