View Full Version : What the hell? (Possible Engine Problems)

05-04-2004, 05:09 PM
Today while grabbing some video & audio of my exhaust, something weird happened, I had it in park, and was reving it up. Normally I can rev into the red, up to about 6k rpms. But today as I was reving it, it would get up to about 4k rpms and then it would go down to about 3.5k and then go back up to 4k and repeat.

If anyone knows what's up, I'd be very greatful to know what the problem is.

When the transmission is in Park, the engine has a soft rev-limiter of 4000rpm to prevent engine damage. What you just described is completely normal.

The car ECU has a rev limiter at ~3500 rpms when the car is in Park.
