Hello
I have a 1989 ford mustang 2.3 liter with a manual transmission.
The problem i have is ever since it has been getting cold I notice it starting to idle a little harder than normal, recently the problem has been getting worse where the car starts to buck hard like you are a newbie at a standard transmision. As soon as you hit second or third gear the car really shakes and bucks hard.
Plugs, wires, flue filter have been changed recently and the cap and rotor look good any ideas??? Everyone so far has been saying fuel pump but I would like to make sure. Thanks
