Thank you very much were did you get the info onthe codes? I can only find a partial list.

One more thing I also have pco231, ip1552 thanks alot if you can help

PC 0231 Fuel Pump Feedback Circuit Low Voltage
IP 1552 Keep Alive Memory (KAM) Error

I got the codes off www.alldatadiy.com (you gotta pay). You could buy a service manual from www.helminc.com too if you want.

Or there's this website too:

Thanks again its people like you that really help us do it yourselfers. Man I know iI have bombarded you with questions but I keep on thinking of things I need to know. If you could do you know how to clear the codes from memory after I fix it. Thanks alot?

They'll clear themselves up if you fix them. They'll actually be in HISTORY for a few more ignitions cycles before they disappear completely. You can of course clear them manually if you want. The last link I gave you above will explain all that. You must clear them system by system. Sorry I can't be more precise right now, but I have to go.

And you're welcome. :)
