hey every1,new here.i have a 96 integra ls that i bought a few months ago.was over heated.Ive replaced the head with one from a 90 teg.i also had to swap the intake cam to one from a 92 cause the 96 cam wouldnt allow it to turn.which ive read on here that theyre slightly bigger.so anywho,once i finally got it running(after adjusting valves and checking timing) it has a misfire in cyl 1 2 and 3.ive changed spark plug wires and dist cap.still has the same problem.i cleared the codes and it doesnt detect it until it warms up,when RPM is low,and when its in gear.(its an automatic btw).

itested the injectors and they all read about the same psi drop except (about 14 psi?)for the first one which which dropped about 11psi.

any1 have any ideas on what to do next?could the injector cause problems for those 3 cyls? or can it be that im using a 92 cam on a 90 head?
