11 year old gas isn't nice (neither are 11 year old tires,belts,hoses) Siphon out the old,put in full tank of high test and some Sea Foam or Wynnes or what ever brand you like. Check air filter vacuum lines,etc. And don't be running around in it until you checked out all the other 11 year old oil,filter,tranny,coolant. Peek at the brakes and I can not imagine the rubber is any good.

1988 MBZ 560sel, just replaced idle control valve, now it won't hold idle, continues to have difficulty starting (usually 4 tries), replaced dead battery (wouldn't hold a charge), am now considering fuel pump relay replacement. BTW, ABS light is on, and the SRS light pops on briefly when I enter the car. Also, the radio was coming on when you turn off the car. Could something as simple as the overload relay cause these widespread problems? 4 Answers
