I've had the B16 for almost a year now, and it has been running great until the last week or so. No check engine light and the ecu isn't throwing any codes. Anyone have a clue on where else I should start.

I just recently changed the oil, went through a tank of gas(not bad gas), changed plugs, cap and rotor. I'm stuck. Any help is appreciated.

 

did u make sure all your plugs are firing ?

 

Yea there all firing. It seems to run stronger as the RPM's increase.

 

any ideas? I unhooked my two O2 sensors on the exhaust manifold and it seemed to run stronger. Could these be bad and the ecu isn't registering?

 

How about your plug wires, distributer cap, and rotor.
