Can anyone tell me how does the car feel when a spark-blowout. I think my car could have bad plugs.

I had a misfire, it went off for two days and it is back, it only happens when I press it hard, at normal driving it does not happens. I it possible that the fuel pump is not working properly? No computer codes detected.

I have a chip on my car, My question is, if there is something wrong with the car, will it turn the light on?

procharger claim the the air to air cooler is far more efective than the air to water, where is it? They did not apply their own theory.

the car idle fine and it runs fine until I wot it had, the misfire goes all the way until red line, could it be the oxigen sensors or the air flow meter? Any ideas please help, to make things more complex I am in the Dominican Republic there is no Ford dealer over here.

the car has a misfire when I wot it, at idle the is no misfire and when I accelerate slowly. It does not bog it is like one cilinder is not firing at wot, some ideas please.
