i wonder how many threads have this title? So, I decide to pull the plugs and knock the gap down to .028 from .032. I felt something at the track last week, and it dawned on me that the spark might be blowing out. So I take the car out when I'm done. The first time I get into, I get a backfire and pop. Do it again laying into harder, same thing happens and the up pipe blows off!!! Pull over and fix that, give everything a visual. Take it back out, try again, same shit. I end up putting a small hole in the up pipe to tb hose in the process!!! Time to waste more of my life that I'll never get back chasing yet another problem. I am just about done with this piece of shit!!
