1995 420e rough idling
I need help.... I have a 420e with about 75000 miles. If the car is driven daily it has no problem, however if it is not driven for about 4 days after 15 minutes of running it develops a rough idle with loss of power (as if it were only firing a few pistons.) This condition persists for about 10 minutes then it goes away.
It is very confusing......
Thanks
