Took the Volvo to the dealer, could not duplicate rough idle, surging and to top it off- All lights reset upon ignition. No lights on when I picked car up. dealership tried 3 times and test drove car with NO symptoms!!! I drove about 150 miles, go out this afternoon to start car -had shuddering, shaking and lights came on again. ETS and check engine. What a FAB car. I then restarted car 2 more times, had same result. Went to get a witness! car did same thing for the 3rd time. The fourth start 30 minutes later the car still had lights but was idling fine!!!! Went back out this evening and same shaking. It is raining here I am wondering if something is wet and acting up!? This 1999 S70 has had the throttle body replaced and software downloaded in 2002 at 91,000 miles. At 124,000 miles had to have throttle body cleaned due to erattic idle. What should I do get a tow to dealer so we can duplicate problems? I am very disappointed -this is a BEAUTIFUL car and drives well sometimes??? Any advice?

Thank you all in advance Michelle

 

If you can drive it there running bad this way you make sure they see it running that way.
