    Hi Codeman,

    Yeah I don't have any aftermarket gauges on my car so it's not that.I tried unplugging all my audio stuff and still no go. I basically tore the car apart trying to find out the problem. SCT now wants me to check the PCMs ground wire.So I guess I will do that.I am glad yours is working for you :). And you were very helpful...thank you for replying back to my message. Take Care.

    Hey I got your message about the error 1019. And what mine ended up being was I had wired my wideband A/F gauge into a location that when I cycled on the key would cause the tuner to glitch. Almost like a voltage surge or something. I would check everything that you can that you have wired in such as your aftermarket stereo. It may seem like it can't cause it but anything that somehow interferes with the signal to the Data link connector or the voltage will cause an error. I am sorry I can't be of more help. Try disconnecting the stereo and trying it. I could have saved myself a bunch of time if I would have just disconnected stuff. And any other things that could be wired in such as security devices auto starts stuff like that. Anything that could be with the PCM or wired into your ignition. I hope this helps.
