    bogging problem

    im still having the same bogging problem with my cb, but its getting worse.

    when im on the highway and i accelerate it fast then i let go of the gas pedal it loses its power and i cant accelerate because it starts to misfire, it sounds like its about to shut off when this happens i have to pull over and sometimes i have to just let go of the gas for a while....

    what causes this?

    Most likely, you need to replace your oxygen sensor.

    Does your CEL come on once you get to highway speeds (about 55mph)? If so, pull the code, and I'll be it's code 43.


    Go to RockAuto.com for a Denso o2 sensor.

      My vote is for o2 sensor also. 809, as I mentioned a couple of weeks ago, I had your symptoms and mine was o2 sensor with no CEL. You car isn't misfiring, it's choking or starving (rich or lean) under load because of what is being spraying into the combustion chambers. Too much fuel and not enough air or too much air and not enough fuel. The o2 sensor sending bad info to the ECU is what causes it.

      I had the bogging at highway speed too. At high speed, heavy acceleration, the bogging felt like an engine knock and my speedometer was dropping fast despite me staying in the throttle. That was a depressing evening b/c I thought my engine was shot. Checked compression the next day and it checked out fine. I was still weeks, and MUCH aggravation away from replacing the o2.

      The symptom that finally pointed to that o2 was the little chugging the engine would do after turning off the ignition. I called it "dieseling" but it's not really that. It's like the crank continues to turn for a brief second after turning the car off. That was the cylinders sending me one final bog to let me know they didn't appreciate the crap I was forcing them to try to burn. I guess it was classic dieseling; in a fuel injected kind of way.

        Any backfiring? If so, you may have a weak spark that is letting unburnt fuel flood the combustion chamber. Check the resistance on your coil, if it's out of spec, replace it.

              Told ya.

              Good... that's what my car was doing. My o2 sensor suggestion was merely my best guess based on my own issues (that I had not yet fixed.) Now I know a new o2 sensor will fix my problem too!

              Don't drive around for long without an o2 sensor. Be sure you replace it with a good Denso or NTK/NGK sensor (no Bosch, which is what most autoparts stores will give you when you ask for a replacement.)
