This new benz I have (85) runs like crap when you first start it. It turns over and starts easily enough but has no power and just wants to die. So far I have replaced the fuel filters, swapped the return and supply fuel lines, and replaced the supply line. The bubble in the fuel filter still seems pretty big. Once the car is warm everything is ok. Suggestions?
