Having problems with your 1994 Volvo 850 ?
1994 volvo 850 - non turbo
\015 I have a rough idle when air condition is off - idle better when air conditioning is on.\015
Try cleaning the throttle body and air idle control valve (IAC). The computer kicks the idle up when the a/c is on, if your throttle body or AIC valve is full of crud it will idle very low and feel rough.
