Big Clouds of White Smoke

[briangoesindie]

Hi guys. I have a 1990 Supra 7MGE manual trans. Over the past two weeks I have been running into some problems. I had a heater hose spring a leak on me, which I mistook for the water pump due to its location, resealed the water pump, found and replaced the leaking hose, and have developed a very strange problem. When I start the car up, and drive around, as soon as I get to full operating temperature, the car starts to miss and blows out big cloads of white smoke for a few seconds until the engine gets up to speed and clears out and starts operating normally without the miss. It only occurs at operating temp. I have been checking the smell of the smoke and exhaust and am fairly certain that it is NOT coolant, but is fuel. It smells chemically rather than that sweet smell(which I have smelled when I have BHG).

So quick explanation of what i have been doing to try to stop this:
-Replaced distributor cap and rotor
-replaced spark plugs and wires
-replaced air filter with k&n drop in
-resealed water pump

So I am kinda at my wit's end right now. I have tried so many things to get it to stop, including disconnecting the cold start injector (thinking that maybe it was dumping fuel into the system when it shouldn't be). The only thing I have left idea-wise is perhaps my battery isn't putting enough juice through the system.The battery has been weak for a while now(i have tested it several times recently and it has passed with a simple "charge required"), but the smoking is brand new. Any ideas would be massively appreciated. Thanks.

EDIT: Forgot to add, I am not experiencing any of the normal symptoms I have had with BHG. No power loss, no over pressuring of the cooling system(altho I have a slight leak at the heater core), no over heating, etc.
