TECH HELP 420E
I have a 1995 420e that has a weird problem. After the car sits for a couple of days it starts fine, but after about 10 minutes it runs very rough and without power as it it were only working on half the pistons. The condition seems to come on after reaching working temperature.
While it is doing this it moves sluggish and stepping on the gas seems to "flod" it.
The condition gradually goes away and after another 10 or 15 minutes it runs fine.
If I drive the car daily it does not do it. It has to sit idle for 3 or 4 days.
