Idle control issue maybe. Getting top of the line mechanics to teach car owners how to fix the idle control on the 1990 Mercedes Benz 300E is getting to be common nowadays. It is but natural for car owners and drivers to allow their vehicles to sit idly for a few seconds to allow them to listen to its engine humming and to allow it to run a few revs while on standby. This is what the idle control device does for the 1990 Mercedes Benz 300E, it minimizes the noise generated by the engine, allows for less fuel consumption and reduces the wear and tear that your engine is subjected to.
