Last week the 560sel was loosing power at 40+mph and almost did not make it up a hill. Monday, depressed the gas pedal and car quit in the driveway. It is Friday, and it won't cold start ulness I pour gas into the air intake, then idles at 1800rpm. wtf? is goin on.

I did check the following for connections: distributor, ignition. cleaned idle control valve w/ brake cleaner. now what?
