Crank angle sensor question? R33 gtst s2

[Almera96gtin15]

I noticed that the centre of the CAS (mitsubishi symbol) is not spinning all the time and sometimes stops all together? I touched it and the symbol spins, even the engine note changes when I touch it. 

Is it faulty? As I get slight bit of a hesitation when boosting also. 

I only decided to check iacv (cleaned with brake cleaner) and check the timing as it was fluctuating on idle. 

Thanks guys.

Yeah, it's not supposed to spin. Spinning would be the bad thing happening, not the occasional stopping of spinning. Care to post a video so we can all do the WTF!? together?

I don't think anything short of an exorcist will resolve the CAS issues you just described but I am anxious to see it. I second the request for a video.

Are the 3 bolts that hold it to the engine in one place tight?

Hahaha lol I don't mean that the whole CAS spins

The mitsubishi symbol in the centre of the CAS. Have a look at yours and you'll see what I mean. 

It's not a casper the friendly ghost situation lol.

The little Mitsubishi sign in the middle of the CAS should not spin at all. It probably got loose somehow(!?) and spins here and there due to vibration. Even stranger is touching your CAS should not cause your engine to sound different, that's why Duncan is probably asking if it's loose. 

 

It's normal timing fluctuates a few degree's at idle. That's what controls your idle speed. You need to lock your timing prior to verifying. If your idle is swinging drastically, you most probably have a vacuum leak. Pressure test or smoke test your system.
