High Idle at 2300 rpm and dumping gas

[mindaugas]

So, last week I discovered that my battery terminals were loose ,despite the fact that the nuts that tighten them down were tight as they could possibly be . So I replaced the terminals and now the VX is back to normal . YAY!

I hope this is my issue as well, I know the terminals are loose. When I start up first time in the morning it's fine. After running for a bit and I start up again, it revs slightly above 1k rpm, then dies. Hit the ignition again and starts right up. If I tap the gas before the motor dies, it's ok too.

Today, while driving in the snow, on a corner, it died. Just shut off. Battery was ok, because still had lights and everything on dash. It started right up, but not before I slid into a curb. thankfully I was only going about 10mph. Ran fine after that, for 3 hours.

Fuel pressure regulator in, no change.
But I had a new exhaust put on and now for the first time I can hear the sucking wind while inside the VX, it almost sounds like something behind the speedo.

So that's it, the intake manifold gasket?
Is the leak in the back typically, and hard to find?

I've checked the manual download and on-line "how-to" but still a bit puzzled.
I can't find a thread with a how-to, is it so obvious and easy no need for a how-to?
