Default Superram Nitrous backfire-----

Well I ran through about 10 bottles successfully without a nitrous backfire. Then my knock sensor wire burnt on my headers which grounded it and took out a lot of timing. I sprayed it not knowing and it backfired through the intake.

Now the car backfires through the intake whenever its cold. If I let it warm up it wont pop but whenever its cold it will. It does it with or without the MAF sensor hooked up.

I replaced the MAF sensor thinking that was it but it still does it....What could I have done to cause it to backfire all the time now when cold??? Hurt a valve maybe???

That's a damn good question...Maybe you have a fuel leak somewhere?
