Engine problem
1987 Lincoln Town Car V8 Two Wheel Drive Automatic 175k miles

The car seems to run ok when it is cold but after it warms up a little and I try to excelerate the engine shakes like it is running on 4 cyls, no power. When it is park or netural an step on gas, it is ok. This happens at all speeds when it is drive. Gave it a gerenal tune up, check timing, change plugs an wires, fuel filter. Checked fuel line pressure an cleaned fuel lines. I am thinking it is a emmision sensor but not sure. HELP.

I had a similar problem and did essentially eveything you did with the same result. My mechanic finally determined after having the car for a month that the fuel rail was rusted internally restricting the amount of fuel to the cylinders. He remembered having repaired a similar problem years ago. Car has run great since.
