I am geussing your O2 sensor is at the end of the header, close to where it exits into the atmosphere. I had a similar problem, I had put a header on my civic, and drove it to the exhaust shop with an open header. It seemed to hesitate, and not what to get up and go. hook up an exhaust system, and that should help matters.

 

well i have an 89 crx with the o2 sensor located on the the tope of my header, changed it and no difference

 

is it throwing a code if so which one.
