Default Engine cannot rev pass 4000 rpms?

Hey guys..

I have a 1994 Acura Integra Gsr....Can't seem to figure out the problem.

The car starts/idles normal....but cannot rev pass 4000 rpms.

Makes a disctinct gagging noise...so it doesn't reach to 4000 rpms smoothly..more like lagging power.

What can be wrong?

Are you sure the car is not in a limp home mode?

No CEL.

Not so certain how to check if the vehicle is in limp mode other than when the CEL turns on and the engine cannot rev pass 6500 or so.

Tried checking for any Codes and no CEL flashes.

What changes have you done to the engine/fuel/etc?


Have you checked the ignition timing?

Do you have adjustable cam gears?
