So I am having a problem where I am losing power down low mainly but some up top. It gets worse as I drive, and if it sits over night and cools off better. But once I start to drive it for like 20 min it gets worse and worse. It’s not the clutch, I’ve replaced spark plugs, fuel filter and strainer have both been replaced. The car is a 2007 Honda Civic lx with a 1.8l engine

O2 Sensors could be going bad. Could be worth swapping out for new ones.

Get Genuine Honda ones. I used an Aftermarket one, and the car suddently acted strange.
