I did a search around Infinitihelp and the only things I could find are possible fuel pressure problem or fouled injectors. Here's a little info on the codes:

and the same thing for bank 2

this thread for a G solved the problem but it was just a matter of running some injector cleaner (STP)

And I think you probably already have this but the engine control service manual is available here:

P1273 came up on my dash too. This is o2 sensor 1 on exhaust manifold correct.I found a hole on my muffler I don't think this will have anything to do with it. Also before it was giving me a code saying bank 2 sensor 2 was no good. Put 800 miles never came back on but this code p1273. What's wrong is it my o2 sensor

I just had my O2 sensor replaced due to code. Would have been >$300 at dealer if it wasnt or warranty. I m sure you can DIY for less

I'm going to do it myself but only if it's the one on the cat if it's on the exhaust manifold no way I can do it it's so tight. But want to confirm if I patch up the hole on my muffler will the code go away or not since it's past the cats one more thing is upstream on the exhaust manifold or on the cat
