One problem related to service brakes has been reported for the 1999 Volvo S70. The most recently reported issues are listed below.
The first time it happen I was pulling out of my drive way. I came to a stop right outside my driveway waiting for it to be safe for me to pull out in on going traffic I push the gas pedal it gave me enough force to pull out on the street as soon as I try to give it more pick up but kinda idle got up to about 40 I would say bout soon as I hit forty it out of no where it wouldn't let me pick up or press on gas pedal when I would it would slow down so I try to push harder that is when the car died so I quickly pulled up on the side of the road because everything was locking up gas it would not let me accelerate my check engine let flash on and put my flash lights on and sat for a minute trying to figure out what was going on. I waiting a few seconds started the car it first let me accelerate enough to coast but in the drive way. My ets light flashes on but doesn't say on. So I thought maybe cause I was low on gas that could a have been the problem I have drove the car all week not a problem at all. So later that night I figure since the street wouldn't be busy I would drive up put some gas in there to see if that was the problem. Got in the car started right up went to the gasstation which is about 5mins from here pulled up in front of the pump turned off car it was a prepaid pump went inside gave them $8 came back out pump the gas got back into the car went to start it nothing so I wanted I tried again got it started soon as I went to push on the gas pedal it died then I turn the key back and try to start it again my ets light stays on this time but ce light flashes goes off some guy tries to give me a jump I push down on the gas it dies. When it died it kinda of sound everything was about to blow up it made a weird sound like a computer as you shut it down. . Took it to a car repair 3mths he had it then after trying all the codes -throttle body is what he said the problem.
