So I've got this old (1985) 190 D 2.2 that I just got back from the mechanic. I took it in for stalling and 6 months later the mechanic told me the diesel injection pump is all clogged with stuff and he can't find me a used replacement. He cleaned it out as best as he could and the car seems to run ok, but there is one issue. It seems that when/if the car reaches 80 degrees C it will stall in park or neutral. Runs fine if it's on open road but if I stop it, it'll stall.

Today, I drove it for about 8 miles. The temp never broke ~65 degreesC. I started thinking that this was more or less the op temp. This led me to thinking that 80 C is too hot resulting in the car running poorly.

Any thoughts?

 

get another mechanic.i never have problems finding parts for any of my mercedes.

 

What about the op temp though? Any ideas what it should be?

 

Do diesels have a lower operating temp than gasoline powered engines?

 

It's not he can't find the part. It's he can'tfind a used one. Brand new diesel injection pump runs closed to 2 grand. He was trying to get me a used one. I too looked to find one and only found a place that rebuilds them for 900 bucks.

I thought the temp was too low. Guess that would explain why there wasn't any heat. This car is gonna send me to the poor house.
