Then I all ready bought new upstream cat converter flange to see if that might work think I should just install new flange and you might be right if somebody else took my car for Joy ride hit something underneath car might be a leak somewhere but we're to first look I thought about upstream converter flange first to change because codes are reading bank 1 so .what you think I should do? Need help thank you so much reading all this information might help someone on here with same problem I have
