I have an 05 civic that has some issues. The car will start up with a weird squeak (just replaced the clutch may have something to do with starter) now that’s not the real issue I’m having. I can let it idle normal won’t hurt anything will rev it up won’t go past 4K rpm in neutral and slow to the acceleration. When I start to drive it acceleration is super slow. And if I go too high on rpm I start to get a popping sound coming from the exhaust. I just replaced the coil packs plugs were replaced about 10k miles ago pulled them (a little black but not bad). I had a CEL light for bank 1 02 sensor and replaced CEL went off and still having same issues. I can barley make it up a hill without it decelerating and almost lose all power. Even at WOT. When it makes the popping sound starts to buck a little. Any ideas?
