My 98 TJ, 4.0, just had the check engine light come on. I was a mile from AutoZone and had the codes read. New to me engine (75,000) have 500 miles on it, no issues (until now). It stalled once on at a stoplight on the way top AutoZone (first stall to date). P0108 manifold absolute pressure/baro sensor high input AND P0463 fuel level sensor A circuit high input. Now stalling like crazy unless, it seems, I'm running at 2500 rpm. Thoughts? (Thanks in advance and merry Christmas)
 
Update: That was Thursday night. I just got to looking at it. I just started it in the garage. It didn't stall until it reached operating temperature. Could it be my post-catalytic oxygen sensor? Do they fail on a dime like that?

Curious what ever happened. How did the issue get resolved. I’m having a similar issue. P0108 code. I replaced the MAP sensor not long ago. I was out four wheeling and ran it all day today. Stalled twice not far from home. Won’t start now.

What brand of sensor did you replace it with? Hopefully a Mopar one, otherwise that could be the issue.

I put the old one I took out months ago back In which was probably the original MAP sensor. The Jeep fired right up. I went for a cruise, no stalling and seemed to run good.

I just bring this up because using anything other than OE Mopar sensors is a well known issue on these Jeeps. They reject the off-brand sensors and usually act up, throw CELs, etc.
