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?

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.

I found out the answer is yes. SUCCESS!! There was a little adjustment to the small plastic tube at the head of the Idle Control Valve, a replacement of a fuse, and voila! It started breathing, at first weak and gasping, but persistent. After keeping her alive with revving the engine a few times, it caught on, and sounded as if it were learning how to breathe again. And now she's alive! It is all good! New ICV ($75.00), new battery ($65.00), (1) 10A fuse, one 15" rim and tire for the spare ($62.00)= $202.00 Awesome!
