Ok, so I have a '04 6spd that I have had for about half a year, and I have had a stuttering issue from day one.
I've tried cleaning the MAF, that did not affect anything. Then a few days ago I got around to removing the SSV and cleaning it and inside the housing. I ran it and it helped the stutter a lot, but it's still there. It used to be very rough at around 7500 rpm, and now it is a very sudden maybe half second pause at around 8000 rpm. I bought a used Cobb AP and installed it with the stage 1 tune, and it completely got rid of the stutter, but only for one drive cycle. What happened was I installed the AP and went for a very long drive. The entire time the stutter was gone. But then the same night I went back out, but the stutter was back. I am no longer going to run the stage 1 tune but and going to get a custom tune done.
But I'm wondering, could the stutter still be there because I did not clean the SSV properly? Was I supposed to dissasemble anything when I cleaned the SSV? Because all I did was spray the valve with carb cleaner and wiped it clean, the did the same for the housing.
Is there possibly anything else that it could be that I have overlooked?
