There is a big difference between cutting out and a cylinder dropping out, which one and at what rev's. Have you had a scan to see if any information has ben logged in the freeze frame on a scan tool.

At what rev's dos it start missing and when it dos if you hold the throttle open will it die or just sound like one cyl is out.

Sometimes 4500 or 5000 its not always at the same revs and just sounds like ive lost a cylinder

any mods done? what boost you running? Plugs gaped right? IIRC If your running higher than stock boost on stock plug gap the spark can "blow out"

I assume you mean valve spring, you don't get a stuck valve spring, either it is broken, weak and the lifter pumped up or the valve it self can stick.

Y does it only do it every now nd then it doesn't do it all the time if it's broken it would be doing it all the time

Going by that statement it is still not fixed, so what did your mechanic say on the remedy. have you narrowed it down to which cylinder is playing up, and I am not convinced on the stuck valve spring theory.

If it was a valve spring it would do it in every gear regardless of roadspeed.
