Niether. Its means the computer detected a problem with the electronic throttle control and turned the warning light on to advise you. Have a reputable shop perform a diagnostic test and check for problems.
I actually have a couple different lights coming on and off. my voltage light and my malfunction indicator light. can i really be having all of these problems at once. oh, and it's overheating. i only have 64,000 miles on my car. these lights don't stay on all the time, they go off & on at different times.
