My car has recently just started to bog after driving for a while. After it starts bogging I will stay on the accelerator and rpm's go up but car feels like its not getting spark or fuel and then all of a sudden it will "catch" and start making power. It will do this no matter what gear I am in even if I change gears while it is not making power. Any input of what the problem might be is appreciated.

 

are running only one O2 sensor on a us-spec b-16 aftermarket headers? if so then thats your problem.

but if your running two, try switching the o2 sensors, the ecu reads and adjusts fuel per pair of cylinders. if they are backwards it seems the ecu has a brain fart and gets stuck in a rich loop. I had both of the above happen to me.

only other thing is your ecu is only reading one O2-sensor. so check your wiring.

If it was an 02 sensor wouldn't it throw a code? I am only throwing a knock sensor code. Could it be anything else.

 

maybe the knock sensor pulling back timing and **** so the motor doesn't grenade?

i would think not, and you're likely driving around with the knock sensor light on, but i decided to throw it out there for comic relif

 

my car does the same thing too at times when its cold my car bogs at times then get power again, i bought some o2's so i'm sure the sensor's i have are gone. Also my A/F meter doesn't work there's no reading or light so I assume my sensor's are gone.
