My 1985 280CE has a slow throttle response when cold. Works just great at operating temperature.

Can anyone help? Does anyone have a vacuum diagram for this car?

It is a grey car with only 665 built. I can not find a motor manual for it.

Thanks

Grey market cars are a losing proposition. The vacuum diagram for your car should be really simple if it really is a CE, meaning coupe, fuel injected. E is for einspritzer, German for injection. The only vacuum for the engine will be for whatever emissions mods were made by who knows and some simpler subsystems. If I were you, I'd check the fuel pump relay, the cold start injector, the air flow meter and the electro-hydraulic actuator. Also check the idle air slide valve. These are all famous for causing or mimicking the situation you describe.
