Having problems with your 2003 Toyota Celica ?
My 2003 celica engine light came on and the rpm's are going up/down at idle
Could be a number of issues. my first choice would be a vacuum leak. start the motor and listen for a hissing sound. a vacuum guage tho would be my first choice. stuck valves will cause similiar problems as well as a failing coil pack. i would investigate a vacuum leak as the first and most likely cause.
