I have a 2004 grand prix gtp. Experiencing slight yet consistent "missing" at idle, an sporadic hesitation upon acceleration. Once it "catches" it takes off as normal. Car has approximately 45k miles. Any assistace would be appreciated. Thx.

 

i have a 2004 prix gt1 with over 100k on it and i had a problem with it missing, come to find out it wasa bad wire, it went away when I changed them out, turns out that one of the plugs was never changed out when serviced because of it's difficulty to extract. Good luck
