New owner with a few questions.
Yesterday I was fortunate to get a 1988 Mercedes 190E 2.3 L. The guy I bought it from used it as his daily driver and I will to as soon as I get a few things fixed on it. The aesthetics of the car are absolutely beautiful given what I paid.
First, they guy explained to me that the fuel pump relay would intermittently over heat cutting power the the fuel pump. He got a new one but said he is still having it over heat but not as often. This morning I turned on the car so it could warm up for about 15 min and as I pulled out of the drive way the engine stopped. I called the guy and he said to turn everything off and pull out the fuel pump replay and let it cool for couple minutes. I did just that and I was able to drive 45 miles and back with no problems at all. Does the fuel pump need to be replaced? Or is it a defective fuel pump relay?
Second, this is pretty low my list but still is pretty annoying. When the car is in drive and is idling it shakes pretty bad but when I press the gas or put it into neutral or reverse it goes away. So when I'm at a stop light I put it in neutral to stop the shaking. The guy said it has something to do with the idle control valve. He said he never got around to replacing it. So, my question is does the ICV need to be replaced? Cleaned? Or is there something else wrong with it.
These two things are the biggest problems with the car. Any help would be greatly appreciated.
