Codes
Thanks for all the help from those have helped me 
I was told there was a way to get the codes from using the dash buttons. Does anyone know how to do this? It would save me from having to borrow my friends scanner Thank Colleen

To Enter Diagnostic Mode
The "diagnostic display" mode is entered with the following procedure:
1) Turn on the ignition but don't start the engine.
2) Press the "reset" button to turn off any warning messages
3) Press and hold "options"
4) While holding "options", press "fuel" four times within a 10-second period.
When first engaged the on-board diagnostics go into an "automatic" mode which shows all parameters:
PCM-TCS-RTD-BCM-IPC-radio-HVAC-LDCM-RDCM-SCM-RFA. If there are no problems, you will see "no more codes" on the ICP
display.
The computer will show two kinds of codes, "current" and "history," designated "C" or "H". A current code indicates a
malfunction is present in the system whose module is displaying data. A history code indicates a past problem.
When the screen displays "manual diagnostics," select the desired module by pressing the "options" button to go
forward or the "trip" button to go back. Press "gages" to go forward or "fuel" to go back.
To exit the diagnostic mode at any time, press "E/M". If you want to erase or "clear" codes, press "reset."
