This sounds suspiciously like a blown head gasket to me, although the timing seems a bit odd (after exiting a car wash). Still, it could be just coincidental... Do you have an aftermarket air intake, like a 'bottom-breather...?'

A blown head gasket doesn't necessarily mean that you need a new engine -- but you could. If it is the gasket, and enough coolant leaked into the cylinders to cause hydrolock, you're looking at major repairs. Or if water was somehow ingested into the engine (as a result of being in the car wash), you may have hydrolocked the engine that way... Further investigation is warranted.
