Ok I just got done installing the nitrous system. Everything went fine. Now after it rained one day, the car struggles to start. It cranks, but doesnt fire. Once when it does fire it runs really rough, sounds like an old muscle car, and some white smoke is coming out the tail pipe. I went back checked all the seals on the nitrous plumbing and found nothing. Also i have never even activated, or used the nitrous kit yet. Now after a couple days everything went back to normal, started right, no smoke, no rough idle. I went to wash my car thinking everything solved its self, but nope, same stuff happening.Im stumped on what it could possible. Any suggestions?

check your wiring, something isnt sealed right
