got the car running the other night, and today was adjusting the rockers. got them all done then gave the car some revs to see how it sounded, it popped, or backfired out of the exhaust pretty loud, also seems like its rich, my eyes start burning after only a few minutes of it runnin in the garage. also everything is new, what could cause this. there are no codes ither, really need some help guys. Thanks...
