my 1994 280 has multiple problems and I'm wondering if all points to 1 fix. It looses power when accelerating (not always) as if it is not running on all cyclinders, but if I restart it, it runs normal. It has a irratating noise coming from the trunk, right side, the engine temperature rises to 100-110 in traffic when the outside temperature is above 90 degress, the ac fans go off and on. Are these mulitple fixs or does it point to 1 item. Thanks
