forgot to mention that it is throwing a code 1 and four i means oxygen sensor right? and also a number 4 which is crank positoning sensor wat is that and like where is it at on my 1991 crx and can that be the reason it boggs out or wat

 

its your crank sensor, had the same problem you have either do not have the all the way in the pins, or you have the backwards....switch them and see what happens,

if you have a DMM check the wires....
