I have a '89 760 Turbo Wagon with 192,000 miles. It has been at the Volvo dealer for pretty much the last month and a half with no success in fixing it. They have now told me they are giving up on it. Basically it runs fine most of the time but for no known reason to me it will occasionally start to cut out when I am driving it. The RPM's and engine power drop very fast, then it would jump around then go back to normal power. Occasionally it will die when doing this. Sometimes it starts up immediately and other times it takes at least 20 tries to get it started again. (I have never had an issue with the car starting before this) Now I am also occasionally having a very hard time starting it in the moring.
The dealer has replaced or repaired:
Various belts and hoses
Throttle Body (cleaning)
Fuel Pressure Regulator
Fuel Pump Relay
adjusted the transmission settings
They have also tested the main fuel pump and it appears to be working fine.
I am frustrated, they are frustrated. Can someone please help?
have the same problem?
