2013 Honda civic LX 1.8L 158k
So the last couple of months the civic has started sputtering upon initial acceleration after starting. If it's a cold start with only 30 secs to two mins of idle warm up time, it will sputter for a few seconds until it hits about 30 mph and then drives just fine after hitting operating temperature. But....if I crank it up and let it idle until it reaches operating temperature, it will not sputter at all when accelerating. The sputter is only noticed when it is under operating temp after a cold start and does not sputter at all afterward. Cold start "take off" basically. My mpg has dropped off from 43 mpg to 36, but that happened before the sputter issue and I figured it was due to the mileage on the car seeing as it is driving 100 miles round trip daily.
Is this a fuel pump going bad? I looked up a fuel filter but it only gives me results for the fuel pump module assembly.
No check engine light at this time either.
