What can rev limit ford 4.0l sohc engine?
I have an old 2002 ford explorer sport trac. I understand that there's a rev limiter when in park or neutral, however mine also rev limits while driving. I know there's a 'neutral' switch somewhere that I will check when I can find it and get a new one, but is there any other conditions that can cause the engine to limit at 3000 while driving. It is smooth and quiet but just won't go above 3000, the car would also not produce any spark when the temperature dropped below -10c I don't know if it is connected or a separate problem.
