Backfire in the intake usually means lean...You say you just put on an offroad h? When mine, and many of my friends put thiers on we had backfire problems...but it was without question through the exaust. You might want to double check the source of the backfire. By the way..welcome to the forum.

I second that notion: Intake-Lean, Exhaust-Rich. You MAY be hearing the sound in the engine compartment running up the smog tube. Investigate and reply...

When is it poping? First few minutes after you start it up? Low RPM's? High RPM's? With the car in or out of gear?

I'd also check what others have recomended here as well.


While you're at it, you should pull the codes from your computer and see what you get.

I mostly had the problem when I was running my car hard at high rpms. When I would let of to shit....BAM!!!!! Very loud, very noticable through the pipes. T-top terror is a friend of mind and knows his shit. What he said about hearing the sound through the smog tube makes since. We really need more info..but we are all happy to help. Again...Welcome to the site.
