I have a 94 h22a engine installed in my 92 hatch. At first I love it then it start giving little problems that I can't fix for the life of me.

The first problem I encountered was that seemed like it would pull very weak to vtec and after. I got a few error codes all pointing to a bad distributor. I replaced the distributor and get rid of the error codes but the car never felt the same. I felt like it lost some power and don't know what is causing it.

A new problem I am encountering is that the car will bounce in and out of vtec a once or twice before engaging. Hard to explain, it goes on, off, stay on or on, off, on, off, stay on. Get what I am saying.

I have given the car a complete tune up. New cap & rotor, new distributor, new spark plugs, new oil and oil filter, new air filter, new fuel pump, and I even cleaned the vtec selonoid screen. The only error code that I have is the one for the EGR which I know causes no problems, I always had it like that.

The only thing that I haven't done is checked the compression and my dc 4-2-1 headers have a slight dent at the bottom (could this be the cause?). I will send pictures of the header small dent later.

What do you guys recomend? Any shop in socal that can diagnose these problems?

 

headers could make the motor lose power when they get dents but then again its probably you tripping. For vtec, If ur not gettin codes right when it happens then u should try using another ecu.
