hey guys I'm new to this form , I just bought a 2008 STS 150,000km it has a engine code look that up seems to be misfiring on cylinder number 3 when I'm going on the highway at 100km it seems to sputter when and when I step on the gas and go over a hundred it goes away and sometimes when I step on the gas hard I feel as if the vehicle is accelerating a bit by itself..
I was planning to change the spark plugs erase the code if it comes back I was going to switch a coil for another one to see if it misfire on cylinder number 2 I was also going to clean out the throttle body
my questions are am I taking the right step?
also I was doing some reading around do I have to remove the intake to replace the spark plugs or on the 3.6DI it is not needed to ? can I do this myself?
also my car is in park and the the display is beeping telling me its not I have to wiggle it around for awhile for it to go away..?
