Trembling/Pulsing Engine Options

[AustenJoe12]

Hey guys, so I have a 95 GT and just recently (like it just started today) my car started trembling but only when I am at a stop light. When the car is idling at a stop light it starts to pulse and tremble as if it's going to die off. I can not only hear the trembling but I can feel it in the pedals. The car is also running really sluggish and I already changed plugs, cap, and rotor (because they were never changed). My car was also sitting when I was trying to get my transmission figured out. I was told that I should change the fuel filter because the car has been sitting for the better part of 6 months with ethanol fuel in it. I was wondering if any of you guys had this problem and what you did to fix it. Anyone that could help I'd really appreciate it.

Try running some seafoam through the fuel system with fresh mid grade or higher in it. It's possible the octane dropped a level and you've got some separation. Wouldn't hurt to change the fuel filter too. Also, if it's been sitting 6 months, it wouldn't hurt to change the oil.
