I have a 1999 chevy 5.7 suburban. For the first start of the day it backfires and is hard to start. For the rest of the day it starts and runs fine. One backfire blew apart my muffler. Also, the service engine light is on. Was told it is a oxygen sensor. Which one I have no clue.
have the same problem?
