I need any information on the performance of my engine.

1993, 190E, 2.6 187,000miles

When I first start it, and the engine is cold, after it sits overnight. It runs great. It doesnt shake, it idiols where at 700 in gear, its noticable faster and more responsive to the gas pedal. I love it. After it warms up though, the idiol drops down and the pedal gets alittle easir to push in. It goesnt go as fast as it did just a moment ago. It also shakes alittle and idiols at about 500, 550 in gear.

I have a K&N filter in it, new plugs and new wires. I think I need a cap and rotor. Im getting one in a few days. Thats all the informaiton I think is relivant.

Is has anyone had this problem before, and its a sensor or something. It just seems as soon as the car goes to idiol down from 700 to 500, everything goes bad. Any information would be great.


Also, where is my picture on my signiture? Can anyone else see it?

Thanks guys.
