We have 1999 Volvo glt. During routine maintenance our mechanic noted that our electronic throttle modulator (?) needed to be replaced. He said that he has seen this problem on many 1999-2001 Volvos. The clue for him was the irregular and high idle of the car. It cost approximately $1000. 00 to repair. The car only has 54k miles.
Vehicle has electrical/brake and engine problems. Brake pedal has a clicking noise, and after the third click, brake pedal locks up. Also, engine failed twice. Failure a result of the engine flooding itself, ruining the spark plugs. Dealer does not know what the problem is. Engine was replaced. Brakes will also occasionally sink into the floor. These problems still exist after being repaired twice. In addition the electrical system has failed several times--the turn signals went out, both headlights have gone out, and the gear shift panel lights have gone out.
