spark blowout?

prinzzz · May 12th, 2008, 09:18 PM

what does spark blowout feel like? when hard shifting 1st to 2nd and 2nd to 3rd im getting a very brief stummble. it feels like a fuel issue but with the 4.10s it never happened, now with the 3.55s it happens often but not every time( like when i took my tuner for a ride, figures). is data logging the only way to diagnose? any ideas?

I had that problem 3rd gear red line 4th gear red line turned out to be a tune problem. MAF count was off if I remember right.

Yeah, 25 thousandths and it finally went away. Been doing good since, battling shitty gas on a daily basis, but no more blowout!
