I have a D16Y7.
I just got a cam installed and I also got my head planned/milled/shaved (not sure of the proper english term) to raise the compression.

Ever since then...I find that my car has some hesitation when I'm at WOT (sometimes even when not at WOT).

I also have EX intake and exhaust manifolds going out through my stock exhaust (no cat...couldn't fit it).

It almost feels as if there isn't enough gas going to it...could that be the problem? Someone has told me that maybe my stock exhaust could be causing this problem. I have bought a Greddy cat back that I will probably be installing next week. I'm thinking this problem could also be caused because I have a CEL (no cat) but someone has told me that this code should not prevent me from running in closed loop therefore should not be a problem.

Anybody have any suggestions???

 

I'd check the timing w/timing light first. When timing is severely retarted the car will hesitate for a second or so...

I forgot to mention...I also have an adjustable cam gear .... timing and the cam gear have been adjusted.

By hesitation...I don't mean it hesitates when I floor it...I mean the pedal will be floored...RPM is going up....after a few seconds I can feel the car hesitate a few times. This usually happens between 3k and 5k rpm. (My cam is designed so that my powerband is between 5k and 8k)
