Engine Performance problem
1997 Other Mercedes Benz Models 6 cyl Two Wheel Drive Automatic 118000 miles

When I start it up I have to let it run for a while or it doesn't have much power and the engine light blinks. In order for it to drive normally I have to turn the car off and when I start it backup it runs ok. Also it makes a whinning sound while im driveing and a small backfireing noise under the front left side of the car. And durring acceleration (like when im passing or just wanting to get on it) it does a pause and never accelerates at all, no power. It still run good over all. Also engine electronics light is on when I crank the car. Thanks for the help.
