O2 sensor stays at .62 range at idle.
Short and Long term fuel term Negative numbers and increase with temp increase.
With throttle position change up and down vehicle parked, O2 sensor values will start to change for good numbers and Short term values go to change going to zero, no Long term value change on OBDII scan values.
Is there a air filter problem or fuel pressure/fuel filter restriction causing this, and what possible repair to fix vehicle high gas consumption. Do not have vehicle till later to check and fix, and do not want to throw parts at it and not repair correctly. Thanks

MAP sensor value at idle and 3000 RPM....Steady? Try actual vacuum gauge and see what that does- hook it to a port engine side of throttle plate. Post results. Vacuum #s and if it's steady , fluctuates constantly or jumpy at idle but smoother at 2-3000RPM. reply?
Also dug up this-
Are you getting a DTC P0172 (fuel system too rich) after replacing the timing belt, the autotensioner,
or the water pump? The camshaft timing could be off. Refer to the Engine Mechanical section of the appropriate S/M, and check the camshaft timing. If the timing is OK, then do the normal troubleshooting for DTC P0172.
You SURE the other code wasn't P0341?? I'm not finding a P0342 from Honda.--How many miles on this one?
IF it is actually P0341 , then you need a timing chain AND tensioner.
Sorry mistake was a P0341 typed incorrect number, I will try the Map check as you indicated when have vehicle and other checks as you suggested and thank you for your reply. mike
As stated you need to check base timing. I also do not find that code number? I would be happy to look at it for you and am local. Give me a call if you have further questions
