All the vacuum lines themselves are pretty new and not cracked where replaced 2 years ago with some 3.5 mm and 4 mm vacuum tubing. Everything was hooked up right, maybe the guy who did the smog did something by accident? Idk. But yeah idles great, but step on the gas and it backfires.. I could post some pictures of the nest of tubes, everything looks to be hooked up right via the diagram.
