Jeep running like crap

[Dutchmen76]

Every time I start my 98 wrangler it ideals fine for a few minutes then Rpms drop to almost 0 then it catches itself and does this repeatedly. I’ve replaced the MAP sensor the TPS and I’m not sure what else to try. Anything would be greatly appreciated

Check for a vacuum leak. Not sure if 98 is different than this pic but gives you somewhere to start. You might have a cut or crack in one of your lines.

x2 vacuum leak. Had something similar and sure enough found a cracked vacuum line. Easy fix for once!
