For about a month or so I didn't start my car (1986 300E W124). I was away on business. It was running fine when I left, when I got back it initially started fine. I went to the bank without any problems. After stopping by 7-11 I started the car and it began to miss. Both at idle and while pressing on the gas. I figured maybe the line got some air so I let it go.

Today the problem persisted. It even died out at a stoplight. It sounded like it was trying to suck some gas. After getting a haircut, I had a hard time starting the car. When it finally started, it missed for a while, then suddenly it cleard up. I made it home without any problems.

I have a very important business to attend to next Sunday. I cannot afford to get stuck. Are these signs of a plugged fuel filter and/or a failing fuel pump?
