Thread: 91 Octane

This morning on the way to work the car stalled while making a left turn through an intersection. Thankfully I did not hit anything because it was hard to steer all of a sudden. Recently I filled up with 91 Octane instead of the regular 87 to see if that would reduce KR. I haven't started scanning for KR because I think its still a mix of 87 and 91 fuel. My overkill tune is for 87 octane. Car started up fine after I got it pulled over and stopped. Drive home was no problem.

What type of scanner do you have? I would scan it anyway. Might see some data to help figure out what's going on.
