The engine has IDLE relearned with the hose OFF. It thinks its really lean so its adding lots of fuel. DISCONNECT THE BATTERY and let it sit for 4-5 min, reconnect it, CLEAR ALL your DTCs, reconnect the PCV hose and start the engine. It will idle a little funny as it idle relearns but,, it should start and idle normaly.
Give that a try.

update
Car started to throw p0200 codes so i started to check injector harness for broken wires i noticed the pcv tube that connects the valve covers in the back of the engine by the firewall was cracked so i removed the whole pcv system all the tubing and rerouted to the front of the engine with all new tubing and pcv valve. Reattached to TB and that's when the car died. Somehow the car is running with the pcv tubing attached to TB, but the idle go's up and down no consistence idle and when i excelerate i get popping and miss firing but no codes i don't know if it's part of the injector harness p0200 problem or the pcv system. I'm lost. Any help would be great. Thanks
