Default h32 and h44

I got h44 about 2 or 3 months ago, and i replaced the driver side oxygen sensor. Car ran great with no issues, until yesterday light came on, and displayed h32 and h44. any thoughts on what it could be? are the codes connected?

thanks

Code 32 is for the EGR circuit--44 means bank 1 O2 is "seeing" a lean condition--If i had to guess (and I am) I'd suspect a stuck EGR valve--if you have a rougher then normal idle-- I'd suspect EGR even more so. There's a pretty long procedure for checking the EGR in your FSM.
