Hello everyone, I had been doing good with my car for a while but, last night driving home, when I would stop on a light, the engine seems like if it wanted to turn off. Same thing today going to work. So, during lunch, I bought a new fuel filter (the small plastic one), installed it, turned open the plastic valve next to the filter to let the air out, pumped it until diesel started coming out, then closed it back up. When I started the car, it had a little "hick-up" but then seemed better so I took it for a spin, everything seemed fine but when I stopped on a light, the problem started again....the car shakes almost like if it wants to turn off. Any suggestions of what to check next?

Thanks Again Everyone,
Adiel
