Help. Possessed VCOM SC engine

This morning at practice my vcom started going nuts. Would cycle itself going full auto (was playing semi) and the velocity would come way down. During the point I was able to turn the air off, back on get a couple shots and then it would go nuts again. When its going nuts air is coming out the barrel and feed neck. Wasn't able to duplicate it in the pits.

dwell is stock and I set my pressures via the sticky with a tester. When I get a chance i'll throw a tester on it again to see what they are at now.

Wondering if anyone has seen this before and what the fix is. Tourney next weekend. Would like to use it if I could. Will put spool engine in later too and see what it does.

Thanks and Cheers

I'm betting that it was trigger bounce. If your velocity was dropping, it may be time to rebuild your regulators.

Trigger does not bounce at any other time. That also wouldn't explain air puking out the barrel and feed neck.

When I get home from work tmrw I'll take it apart and clean it etc.
