I have a 1993 400E. I have a problem with the vehicle hesitating after sitting for about 3 days. If the vehicle sits for about 3 days, it will have bad hesitation to the point it almost stalls unless I put it into neutral. Anyway, it will clear up after about 7 miles. I tried to take it to a local mechanic and by the time I got there the car ran great. I tried replacing the plugs, but it didn't make any difference. Any suggestions would be appreciated.

lots of things can cause this. gotta start someplace so
suggest that you leave it at the shop for three days so
fuel pressure and such can be checked.
or don't let it sit for three days.
