I have an 08 mustang gt and when it's warm and doesn't happen all the time but very often it pops a lot past about 4k to me. I have cherry bombs so no mufflers pretty much. Is that normal? Checked spark plug today and looked normal. Was gonna change them but they look fairly new from the previous owner. Coil pack still had fresh dielectric grease
