DTC P0172 and P0342 any correlation?

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.

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
