I'm experiencing what I think to be spark plug blowout, but I JUST checked the plugs, gapped them all to .028, and they are the BKR7E plugs that everyone raves about here. What now? Also, if it matters, I have a 2015 Eco 6MT with about 7,500 miles on it.Same for me WhitenBright. Had a rip in a boot causing "blowout like sputters". Either way, if you start feeling the blowout sputtering, check the general area of the coilpack / plugs.
