won't always idle

My 92 F250 with a 351W won't always come down to idle after coming to a stop. If I put it in park, it will race until I stomp on the gas, then it will come down. It acts like the choke is stuck on a carburator, only I'm missing the carburator. I was told it is sucking air from somewhere, but it seems to be sealed up. I've sprayed it down with carb and choke clener to see if it will suck it in through a vacuum line or a gasket, but nothing happens. Any ideas? Thanks

Sounds like you have sticking throttle linkage, try freeing it up with a spray lube (not WD-40).
