Stock or after market ecu??? Manual I take it too

Well the throttle was closed, my foot was off the accelerator. Still went to red line - should have been idling.
Every time I turn the engine on, straight to redline.

The engine won't rev unless the throttle is opened. It won't overrev unless the throttle is opened a lot + load is light. Sometimes this occurs when the clutch is slipping.

Aftermarket ecu? Ecu stock should have rev limiter shouldnt it- stoping this

Hey guys,

just taking the car for a drive when the engine starts over revving. When I mean over revving I mean to redline and beyond so that I could hear valve bounce.

I checked the throttle cable: all ok, not staying open.

The only other thing I thought it could be was a broken fuel regulator.

It wouldn't stop revving until I turned the ignition off. It did puzzle me that it didn't run out of air even though the throttle was closed.

any ideas?
