Hello there,
I just joined this forum and all your feedback would greatly be appreciated.

I owned a 1994 s500 and it runs really great. However, whenever I don't drive the car for a week, the problem is starting to kick in.

1. First start the engine, the car seems to be ok and seems to be drive-able. But after driving for awhile (20 miles or so), the car could not accelerate it and the engine slowly dying out even though I try so hard to push the gas pedal.

2. After the car completely stop, I could not even start the ignition and I have to wait for another half hour in order to restart the engine in order to drive. Once this works, the car is drivable again. It always happens like this when I don't drive the car for couples of days.

Please advise.
Thank you
