02 sensor issues

Just got the red might morphine power ranger back from the shop and got a new coil and a timing chain gasket replaced as well as got a new transmission installed. only set me back about $1500 for all 3. don't ask how i did it but understand it took 3 weeks to get it done.

anyway, got a new check engine light on the red ranger and its a p0155 code and a p1151 code. i believe the o2 sensors probably bad as they haven't been changed since birth and there are 142K miles on the engine.

what i am looking for is anything else i should check while i am up in da engine changing stuff.....

P0155 is bank2 sensor 1 heater circuit, most likely the the heater in the 02 is open. P1151 is indicating lean on bank 2, so possibly intake leaking? or could just be that o2 getting slow.
