Poor Idle
1999 S40 2.0T auto.
The old S40 is suffering with its idling. I seems to me to idle to low, sometimes causing it to cut out. When i start it up from either cold or hot i have to 'blip' the throttle otherwise it takes ages to start or doesnt at all. When cold it idles in gear at 900ish rpm, once warm it idles at between 400 - 600 rpm as indicated by the rev counter. When it idles at 400 rpm there is a vibration which i think is from the engine reving to slow. Once running the car preforms well. I have searched the forum and i seem not to be alone. I have just had the car fully serviced and was told that he couldnt see anything immidiatly wrong ( he did say he doesnt have Volvo software for his diagnostic machine). I see some people have cleaned the idle solinoid and the throttle body, how is this done??? did it work?? In the absence of a Haynes manual is it the bit behind the air filter, and where is the idle solinoid? Thanks Simon |
