Engine Popping 3000 RPM


Recommended Posts

99 Civic / 94 D16Z6 swap


What causes the engine to make slight popping noises around 3k RPM before I shift?


It's like a motor backfire or something.


It's not really loud but it's noticable from inside the car.


I changed the spark plugs and it helped a little (I think), but it still does it.


The old spark plugs had oil on the middle-top part, valve cover gasket right? I bought a new one but didn't put it on yet.
