Oxygen Sensor ¿Q?

ok i gots a small problem but i think i might know what it could be but i dunno, well the problem is that my car stalls out iwhen i gas it up out of an idle but then again i just rebuilt this beast and now at the end of the turbo i had to put some red silicone to seal up the exhaust pipes but if that silicone was to burn for being too much of it and is exposted to the inside of the pipe will the smoke do anything to the oxygen sensor that sits at the top of the turbo cause my car to stall? btw the car i'm speaking of is a 87 supra turbo and if it is what should i do about it? run it till all the silicone burns away? :D oh and yeah theres alot of smoke white smoke looks just like the smoke from when i decided to burn the gasket maker silicone hehe

any help would be useful
