Hello
I just got a 1987 260E as my semi first car. My other only lasted 2 weeks before catching on fire. But, my benz is having trouble. When i first start it up and the engine is not totally warm it runs fine for a few block. But, when it hits about 80C it starts to die, it will only go 1kRPMS and 20mph. If i hit the gas it tries to die. I have to nurse it for about 2 block then it runs fine. I thought it was a dirty fuel filter so i replaced it. It stars easier and runs better but the problem hasnt been fixed. The fuel pump makes a whining noise but always has. Once problem may be that a few weeks ago i ran out of gas. The person who brought me gas used a dirty fuel container and that put lawn debris in the system. I ran some b12 chem tool but still, it cuts. The tranny shifts hard but only need s good flush and refill. Does anyone have any suggestions? Thanks.
Ben

Flush the tank, and bring the car to a shop to clean the fuel injectors... I think so
