    ok the b18a1 is in my 89 crx hf, its all wired up and it starts but wont run for long
    its running really rich, nad im getting a CEL saying its the intake air temp sensor, i pulled off the connector to that thing and theres no power there. Would that make the car run like ass? i tried to trace the wiring back and see if there was power in it but there was nothing at all. Anyone have any suggestiongs im just ready to get this car running.
    any help is very much appreciated

    do you have the right connector going to the IAT sensor? should be 2-wire connector with red/yellow and green/white wires - EACV has same type connector with blue/yellow and black/yellow wires
