2002 Ford Taurus running rough
My car has been running rough for a while now, and it mostly shows up
when I first start the car in the morning or after the car has been sitting for
several hours. After I've driven it for a few minutes it seems better. So far I
have tried adding fuel conditioners, replacing the spark plugs and wires,
replacing the fuel filter, and replacing fuel injectors. When I took the
manifold cover off yesterday I noticed that the lower portion of this hose
(circled in picture) was not tight. Could that be my problem?
