Can you have a bad 02 sensor without CEL codes?
I'm still having bad bogging problems.
My 1993 Civic DX has a d16z6. I just changed the EX ecu back to the DX ecu and it still bogs down bad once the car pretty much warms up. There's also a loud HISSING, or a STUTTERED HISSING to accompany the bogging.
The spark plugs are partially black and partially white and the car smells like it's running rich. It's also misfiring, I think. Like "putting" at Idle once the car gets warm.
I'm going to try to change the Fuel Filter to see if that helps.
The car isn't throwing any CEL codes, also.
