yo i know how to check your ecu codes, you gotta get to the ecu under the dash and then turn the ignition on and look at how many times the red LED flashes in the center of the ecu, then do the 1 seond, half second count thing i told you about, the ecu will flash once though to tell you that it is on, hit me up if you want me to come y and check it out for you. tyyl holmes
