Miss with 87 octane but not 89
Hi all. I've been trying to figure out a missing problem I have had for quite a while now. I have finally figured out that it only happens when I run 87 octane. It doesn't knock or anything like that. Just misses when under a load, like cruising in overdrive and pressing the gas but not enough to downshift, or if I floor it it falls on it's face in the high RPM's. Normal driving it is fine. 89 octane everything is fine all of the time. Any ideas? Thanks!
