Was headed to work this morning, started up the car and left, ran a little harsh when it first cranked up but didn't think anything of it due to the cold. Parked it after 20mins of running, tried to crank it again, cranks and it would almost start, but then would give the sound of pressure sort of releasing from the motor. Has new opti, wires, plugs, fuel and water pump. Tried starting with the hood open and i noticed i had some smoke coming from underneath the TB, dunno if that was just extra oil burning off of somewhere or what because i was in a rush. Any ideas? haven't had a ton of time to look through it yet
