Why would I not be getting any codes from my ecm? When I hook my analog meter to the connectors it makes the needle sweep but doesn't give any pulses. It's a transplanted 4.0 into a 87 Bronco ll. The motor runs with no issues but it has a slight miss that I'd like to get out of it. The emissions lite on the dash lites up on start up but never after that. Any thoughts?
