Knocking/Missing in 94Z28

My 94 Z28 only has 47,000 miles on it. after warming up/ driving for 10 minutes it starts to knock and miss badly. I know this is most likely the Opti system, but i was just curious if anything else can cause this?


Thanks

Could be a bad or clogged injectors or a faulty 02 sensor just to name a few things but your right most likely its the Opti. Good Luck
