Two problems related to fuel delivery have been reported for the 1999 Volvo S80. The most recently reported issues are listed below.
Prior to the failure, the idle of the car would surge up and down at an idle between 500-1500 rpm's. Trying to park the car the car would jump forward at each surge. A couple of times as my wife was driving the car died on her, one time around a corner and she could hardly steer. The car would only surge if the foot was off the throttle, therefore it would stall as you tried to corner or went to hit the brake. Another time it stalled was in a traffic slow down on the freeway. The part finally failed one day when the car just would not start. We had to have it towed to the dealer where they replaced the throttle control. Two more times after the tc was replaced the car started to surge again. At those times as soon as the car started to surge I brought to the dealer. Because it was the same part that was replaced there was no charge. The dealer told me they must have been defective parts. One more time the car did the same thing and I returned to the dealer and once again they supposedly replaced the tc and told me that the flame trap was the cause of all the problems and needed to be replaced. Since they wanted another $1000 to replace that part I decided I would do it myself. The dealer told me they would not warranty the tc anymore. After I replaced the flame trap, which there was nothing wrong with it, 6 months later the car started again with the same problem all aver again. That's where I am at now. Originally when the car died and was towed to the dealer it cost me $1390. They replaced the mass air flow sensor $222. 53, the throttle body $573. 10, gasket $3. 44, etm reload $35. 75, labor $439. 75 and tax. This occurred on July 3, 2003. The car then went in several times for the same thing with the last being may 18, 2004. And now we are back to the same problem again!!!.
