My car has a hesitation that usually happens at around 3,000 rpm. I have searched and searched and thought I had the problem to be a knock sensor.

Car has about 157,000 and I am the 3rd owner.

So I replaced the knock sensor, cleaned throttle body, EGR tube, IACV, and the Upper Intake. Car still has the hesitation. I searched more and found that coils can do this as well. So I tested all the coils resistance and two were at 1.7, two were at 1.4 and 2 were at 1.5

So my question is, is this a good resistance? Are the ones with 1.4 and 1.5 close to going out? Or should I be looking into other areas?

 

I measured mine when I changed the plugs and they were all around 1.5K. I think that yours are still OK but the higher resistance ones (1.7) should be watched.

 

OK cool man. Any other ideas what could be causing it? Its CALI Spec, so I was maybe thinking one of the cats could be plugged up or something
