Rustfarmer nailed it. Its your catalytic converter. Pretty soon you will have starting problems. I just did this last year. Mine would barely make it past 45 mph.

It could be anything because of the electronic/computers,etc., that cars have internally now days. It could be a fuel injection problem, or an electronic timer that is holding it down under 55 mph. The control logic in your car's computer could be holding it back. Have a dealer check it out, or get a computer diagnostic auto analyzer which plugs into your car to scan your car's internal informative computer to find out problems digitally and electronically.

Many possibilities, but if it runs well otherwise, check for bad cat converter.

Vibration when accelerating from stop


Acceleration is the rate of change of velocity over time. When you are braking, you are changing the velocity of the vehicle you are in. That means that when you are braking you are actually accelerating.------------------------------------------------------------------------------------

2003 Expedition engine light flashes on/off when eccellerating took to Auto zone, code was P0301, changed out plug and COP still doing smaething. It sputters when accelerating. What wrong with it?


First, are you certain you changed the plug for number 1? If so, check the power connection to the COP. If it is dirty or loose that can cause a misfire also.
