Jump the connector - read the code. Report back to us.

Can't really tell you what can be wrong. Have you tried actually using an OBDII computer with the car?

i can tell you right now that the reason vtec pulls so hard is the fuel is ALL wrong.. if you swapped in a h22a4 is has 290cc injectors and trying to run it with a p13 ob1 expects 345cc so your was under fueling the car.. second i hope if you are using the 290cc obd2 injectors you removed the resistor box also the p14 expects 240cc injectors so if your runing the 290cc witht he p14 your runing too rich

best peice of advice stop mixing and matching ecus and motors. what ever electronics are on your car thats the ecu you should run. also im willing to be you have a fuel related code, probably o2 to rich or o2 to lean..

 

AWESOME SOUNDS LIKE THE SORT OF PROBLEM .... good honda-techer


car is still acting gay but will look into it
