2004 Honda Accord, 2009 Honda Accord, 2010 Ford F-150....even a 2012 Ford Explorer that’s had the same fault once or twice, here.
I suppose the humidity and moisture could be a factor. Count yourself lucky.
So far. Don't get me wrong, I know what alcohol does, I just don't understand why it seems to affect some really bad, and others not so much. And humidity is about the only thing I could come up with.
Just one time leaving methanol in my carb for two weeks left it so caked with salts it wouldn't do anything. That's why I know it's crap as anything for normal driving. Racing is okay.
