White smoke coming out the tailpipe after replacing Spider injector

What is your question?

Fuel pressure regulator on the Spider injector was leaking and dumped a lot of gas into the intake plenum replaced the Spider injector assembly whole thing and now it's idling rough and there is a lot of white smoke coming out of the tailpipe after I start and it has been running for 2 minutes to 3 minutes

What makes this problem better or worse?

I don't know I haven't let it continue running

How long has your 1996 Chevrolet C1500 had this problem?

Just started after replacing Spider injector assembly
