Answers :

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.
