Thank you for the reply, When you say "blowing the carbon out" what do
you mean? I am in Austin now, I did notice some places have 86. but I
am pretty sure we have 87 here in town... Also, in CA they used
Oxygenated fuel (if i remember right, they also have MTBE) and now
that I am in Austin, i dont think any of those are in there...

But its more expensive and I'm a tight wad! :) j/k.. actually in the
TJ manual it actually states NOT to use Midgrade or anything higher
then 87... So i was concerned...

Thank you for the replys!
At first i figured it was a brand problem so I have tried Exxon, Chev.
Valero and Diamond Shamrock (which are one and the same) and those
are what I use to get in Ca.. Also, i am at 900 ft elev here in Texas
and in CA I was at about 300 ft.. so not much of an elev difference...

The midgrade fuels or premium fuels won't damage anything. They just cost
more. Also, you may want to try a different gas station. Avoid the Holiday,
Clark and C-store type places, as their gas is sometimes not as good, even
though the octane rating is the same. Also , decarboning the engine like
someone else mentioned, may cure your problem.
