Check engine light stays and blinks on a 2005 pontiac grand prix gtp and it also has vibrations as u drive


Sounds like it is misfiring.
Try changing the spark plugs and you MUST run premium fuel.

1999 Grand Prix GTP. Catalytic convertor fine.


Make sure it always gets premium fuel...even with premium and especially in warmer weather the GTP will frequently perform the factory programmed KR (knock ******.) In WOT it is also more susceptible to running a lean condition with stock programming.
Things you can do to troubleshoot the problem and give more consistant performance with the GTP is run colder range copper core plugs and/or any brand of cold air intake, or even a stand alone 9" open element cone filter. Both are better than stock and provide more airflow even though the stock airbox was redesigned in '99. What else you can do is not limited to that but a start. Good luck.
