Some times my motro will studder whlie at an idle.Yes it has new plugs,ran a can of sea foam fuel system cleaner.It does feel like a a clogged injector but i have took the steps to fix the problem and it still seems to be there.feels like a loss of fuel pressure or air in the line.I am getting around 230 miles to the tank.Any idea what i cloud check next??:banghead:
