Well last week I tried 89 octane in the 'stang. Shortly after I put it in I posted about a flat spot occuring everyonce and awhile, like the car is pulling timing. I decided to keep an eye and a ear out for anything unusal.

Put in another tank.

Nope, sorry she don't like it. The car just seems funny, runs funny, just yuk! I know that I should be able to run it with no issues, but I don't know, the car is doing something and it doesn't seem to be good. I can't hear any pinging but then again I can't hear much with my exhaust.

I put 93 in last tank yesterday and all the wierd flat spots have gone away, it runs different (better), and eveything.

1 bad tank I can understand 2 bad tanks in a row I can't. She likes the 91+ stuff so I don't plan on putting in 89 anymore.

I just find it strange the way it is/was reacting to the gas.

Pretty much, just an x-pipe, catback, and scilencer removed with a high performance filter. Nothing else.

We have crappy air up here man!!! Although we are just about at sea level, humidity is nasty here and it doesn't exactly have to be 80 degree's for it!

I get nasty pinging when I run 87.
