Bought a 2009 Fit Sport a month ago. It had a p0303 code when I bought it so I replaced plugs and coils. Cleared code and was all good except got a p0141 code after washing engine (my fault). That cleared as well.

Had a p0171 code that was fixed today with new injectors and valve ​​adjustments but the p0303 code came back and car went into limp mode. Called the mechanic who came and cleared code, car ran fine and no misfires when we drove around. He didn't see anything wrong with scanner numbers. Later this evening the p0141 code came back.

Any ideas? Wiring issue? I swapped coil from 3 to 1 and plug from 3 to 2 to see if an issue with those.
