Well last time I made a topic about my hesitation. The car would hesitate at around 2,800 to 3,3000 rpm in every year. It feels like as if something is pulling the car back at around those rpm. I have check everything I could such as spark splug, wires, rotor, cap, fuel filter, and even Ignition timing. THe car idle fine and drive fine except for the hesitation problem. Someone help a brother out.

 

check your o2 sensor...

 

I'm not sure if the primary o2 sensor is fine or not, but I do have a single code for a secondary o2 sensor. I though that a secondary o2 does not affect the performance? Or does it?

 

what are you running?

 

i had the same problem with mine around 5g but my problem was my ghetto filter i had..it wasnt gettin enough air at high rpm

 

The car is stock with 4-1 jdm header, jdm cat, 2.25 piping. Hmm an air filter...interesting because this start happening a while after I put a new one on. I might check that out.

 

Well it aint the air filter that for sure. The hesitation still occur. It so freaking annoying for dailing driving...this is helpless for sure..
