Re: PING again. Tested Fuel pressure. Came out ok.
 

Unless they've changed aviation fuel in the last couple years, then DO NOT
run any through your Jeep unless you don't have a catalytic converter. They
are not compatible with aviation fuel.

Try octane booster, then... that's what I'm getting
at. If it's a compression problem, then upping
the octane will cause it to go away.

Yup, much better suggestion. AV gas messes up a converter in a hurry, and
may also play havoc on an oxygen sensor. It sure was nice to use before the
days of emissions though. I lived about 3 miles from a very small airport
(only private planes now) during my early hot rodding years (I'm now about 8
blocks away from same airport). They still sell us AV gas if we want, but
it's more expensive than the Turbo Blue racing fuel we can get.
