I have a 94 Civic DX that origionally had a d15b7 in it. This engine recently had a pretty bad head issue and one of the pistons didn't get enough pressure, so I found a d15b1 and just finished installing it about 30 minutes ago. It runs pretty funny in my car but ran fine in the other Civic I got it from. Would this be because I didn't change out the ECU or is there another issue?
