This code comes up then goes away every couple of miles…

 

P0174 - Acura Diagnostic Trouble Code (DTC) Definition, Causes and Diagnosis (dtcdecode.com)

 

Okay thanks, fortunately I know what the code means just the fact that is go on and off

I hoping is a leak somewhere
I just replaced the fuel pump Assembly

 

How many miles do you have? Fuel pumps rarely go out on these. If so, you would see both banks too lean.
Anyway, I would lean towards a vacuum leak or valve adjustment/spark plugs. That latter moreso since you say the light goes away.

 

Thanks for you reply, I will take it in to check for a vacuum leak
