Enging Shutdown Problem..Help!

[rivs]

you know what?? it also happened to me that when i shut engine off it kept cranking, in a way that i had to put it in gear and let the clutch out and step hard on brakes to be able to shut it off. But it happened only a couple of times, not anymore. KOEO i get a constant 85, i can't do a KOER because it starts bucking and missfiring before it reads anything, and shuts down the engine. Code 85 is canister purge circuit failure, I eliminated all smog equipment and the plug between Engine coolant temp sensor, and idle speed control, wich is for canister purge solenoid is hanging loose. Ill try to find one but i dont understand why it shorts everything out!!
