no, really. i just came back from the shop and the guy told me there's no real way. not even resetting the codes because that sends off a signal that it's being reset, then you gotta wait. i got money to dick around with to fix o2 sensor problems. and still haven't found why i have a cyl 1 misfire (i've checked the plugs and wires) i thinks it's parkway ford's fault for sending me a crappy head (since they were lousy with service, didn't send all the parts, and they sent me one cracked head first shipment). only thing i heard is buying a chip that goes into the obd port and tricks the tester but i never actually seen one. any ideas?
