I have a 1996 chevy tahoe i changed the o2 senc. all 3.The truck started but runs reallly rough and backfires by the back o2 senc.The Vacuum line by the driver side firewall is on it.But, If i remove the line it clears up for a short time about 10 minutes then idles fine and starts with the backfiring again.. i have not driven it yet.
