Should i be worried?
My check engine light just came on today and the car has been backfiring quite a bit. but it is driving just fine...am i just running a little too rich right now???
I had the same thing happen to me. Got my LT's installed....car drove great....then while cruising around randomly....it seemed to misfire like a bitch.....then the car went crazy lean....then drove fine after. Check engine light on and everything....ended up being a bad O2 sensor.

Sometimes the codes are not always right, just to let you know. We had a car at the shop that was throwing numerous codes, cam sensor, crank sensor, maf sensor codes, and a random misfire. The car would run only if you gave it gas, and it turned out being a clogged catalytic. We cut the cat out and it ranned perfect. Go figure...
