In further reading, I found a post where someone was talking about bringing a Jeep from Arizona to high altitude, well that's exactly my situation.
My 98 came from Arizona and now it's in Telluride, CO elevation 9800 feet.
I don't notice any issues when driving the car though.
My 97TJ had same problem, I moved from Atl,Ga to Montrose,CO. When I wheeled offroad in hi altitude my CEL came on and it ran rich and sluggish + it pingged alot at any altitude, I had to run it on premium fuel.
I changed 3 sensors (Map,throttle position,& idle air valve)& cleaned throttle body..NO CHANGE still code p0107
I read on a forum somewhere about a similar problem and it said to go to dealer and have TSB #180800 flashed PCM (up date computer software)performed.
I had this done and it took care of my problem
Runs great, back on reg. gas no or very min. ping.
Best $150. that I have spent.
Hope this helps others. Rob
