    93 suburban 350 tbi when i turn the key to the on position the injectors run wide open and fill up the throttle body before kicking off then when truck is started the injectors run wide open causing the truck too flood and run really rich and white smoke comes from the exhaust and smells really strong of fuel then when you put it it gear and give it gas to take off it trys to die out unless you feather the throttle. i have replaced the injectors and the inject body that has the star bit bolts and the tps and the cts also what could be causing this
