could problems with my DISA cause rpm fluctuations, actually its more of a bounce that happens sometimes during accelerating from a stop/slower speed? its almost like the car is gasping for air or having problems getting the fuel it needs but it works it way thru the issue very quickly, I have inpa but so far haven't been able to find any information on what values I should be looking for or at in order to determine where this issue is coming from.

 

Have you done a transmission fluid change and reset the values. Start there. Some had fluctuations issues and low fluid was the cause. I'm sure it has not been done so I would tackle that.

You can pull the DISA off and visually check for mobility. If all is fine then there is nothing wrong with it. Also pull a spark plug out and make sure they are the correct ones. If not pony up $$ to get the right ones. I had a friend who put copper ones in and it ran like ......

 

well the original owner had started getting misfires in 2 cylinders so he took it in for the 100k mile tune up which they changed plugs an the misfires went away but shortly after this lil issue started, when I went to the dealer they told me its not the tranny based off the symptoms as well as the car not throwing any codes or going into limp mode at all, im wondering if maybe they used the wrong plugs, any idea on where I can find the correct info on the right plugs to use so I can check the ones in there currently?
