hi i buaght a b18a1 motor with a b17 gsr tranny obd1 and when i ran the car it runs fine it just bogs and the check engine light is on. when i put new headers only cylinder 1 and 2 turned golden on my headers on cylinder 3 and 4 and when u take out one spark plug at a time its sapose to lose power like you can hear it but cylinder 1 and 2 does not change. i swap the spark plugs from 3 and 4 to 1 and 2 but its still the same and i check the spark plug wire by putting it close to the motor to see the spark and also to the dizzy and i see the spark.

do you think its my fuel injectors or what is it

my motor is not knocking at all
