Need some help. I have 88' 300 TE, with a 117 m on it.
My mileage has drop down to 12 to 13 some times 10. When the car is cold it starts fine but after it is hot it has a hard time starting you have to push the fuel pedal down half way to get it to start. When your going down the road and put it to the floor it blows a large brownish white cloud out. I know they don't like city driving.

I have replaced the pulgs, wires, cap and rotor, new air cleaner. It seams to be running worst after the plus and wires went on.

Thanks
Chip
