    Is a rev limiter needed? What for?
    Can it be taken off?

    Well, it seems that GM played with different types of systems, but the latest of these will keep the top speed to something respectable and the rpm to something respectable so neither limit can be exceeded.

    Earlier models just turned off the fuel rail at a certain speed and would not allow high RPM's in park.

    Yeah mine is only when I'm in park or nuetral I can't rev past 4000. There is no need for me to because it's not like I'm racing with an 04 Sunfire LOL. But I just wondered the reasoning behind GM doing it! THANKS

    Limit top speed, limit accidents and make it so the police can catch up to the crooks.

    Limit RPM's. Limit engine damage. Keep engines from blowing up implies more reliable cars.

I have a 2005 Pontiac Sunfire. The instrument panel cluster does not light up, nor does the radio buttons, fog lights, tail lights, gear shift light or the a/c, heater light. We've changed several fuses for the above and this has not fixed any of the problems. What else could it be? Thanks
