I am going to be driving around today so I will see if it keeps stuttering. If it does, I will try to have it uninstalled and see if it helps..
I was doing some google searches on "JB4 Stuttering" and from what I could see on some other cars with the same problem could also be from 1) Spark plugs may need to be replaced 2) Could have something to do with the fuel pump
