Hello,

On my 190e I have had some random occasions lately where when i am driving the car suddenly will not respond to the gas pedal. Things I have noticed are:

1. When it stops responding the rpms stay where they are until the car stalls about 10 seconds later.
2. When i am pressing and depressing the gas pedal the vaccum gauge moves as expected.
3. After stalling it seams to take around 1 minute or more to get the car running again.

My question naturally is what could be the cause of this?

My suspicions are that it is fuel related, since i dont lose any electrical power. And the car runs for a short time after i loose the pedal response. It almost seems like its just using up the remaining gas in the lines.

I could think of the following:

1. fuel pump
2. clog in fuel line - doubt as i think the problem would be more frequent.
3. fuel filter - doubt as it was replaced less than a year ago
4. fuel injectors - doubt as if it was one injector I would think the car would stumble but still run.
5. fuel pressure regulator
6. fuel distributor
7. fuel pump relay

If anyone has encountered this before please let me know what you found, or if any one has any ideas on where i should start please let me know.

Many Thanks,

Josh
