i recently picked up this 93 190e 2.3 red on black. When you floor it to the kickdown button, the engine rpms will rise but the car wont move. Doing so from 3rd gear at about 40 MPH it will hesitate until you let off the gas then it will pull and accelerate like it should. The car drives perfect except for this and is very slow off the start and the transmission has that quick crisp fast first shift, this is normal with others 190's???? I have no idea what this could be, CIS was tuned, fuel injectores checked, dont have a clue...If anyone has ever had this problem, and they know what it was i would greatly appreciate if you could make a reply. Thanks again.
