My 98 lexus sc300 has the traction light flashing and the check engine light on. The car won't drive. Engine RPM stay at idle no matter how hard i hit the pedal. After a few turn on/off with the ignition key, the problem gets worse. Now the car starts but the engine imeidately dies. Can someone tell me what the problem is and how hard/expensive to get it fixed? Thanks in advance

Update: I went out and tried again and the engine started and stayed on. However this time when i pushed the accelerator pedal all the way down, i get some RPM increase and the car drove. To keep it going i had to push the pedal all the way down and it only ran 10-15 mile per hour. Any idea?
Thanks

Get an obd2 reader from someone and check to see what codes come up and move from there. Or buy a reader. Many parts stores check it for free but since your car isn't running, you will need to borrow or buy one. It takes 5 minutes.

if you have advance auto, they have reader to lend you..

i'll try to find a reader. Where exactly on the car that i need to connect it to?
thanks.
I found it. I'll post the code as soon as i can get a hold of an OBD2

i finally got ahold of a scanner. The code is P1125: Throttle Control Motor
Circuit Malfunction. Can I fix it myself or i have to bring it to a shop? Any idea how much it will cost to fix?
Thanks
