Mmmmm, usually the vacuum hose replacement doesn't require the engine to be removed. It will take time, but you might want to double check all the routing, if your not careful to do one at a time, it's easy to make a mistake. Check valves are a bit easier, but worth making sure they're working normally. Finally check the BOOST SENSOR, the small black sensor mounted on the firewall near the throttle-body with a single vac hose leading to it. If it's unplugged, it tends to give similar symptoms. It also sounds like it might be flooded now so I'd also check your plugs.
