tune up's skipped is #1 cause on earth, egr stuck open. (if it has one, mine didnt on my 4.0L (x3)) no engine stated, so i guess at parts, due to that.
the 1997 any scan tool on earth works, on it.
if the scan tool shows DTC errors just before the ASD drops
bingo, no more guessing.!
does the ASD relay drop just before the stall?
low idle means misfiring, and the endless list for that.
air leaks cause faster idle on all map speed density systems, like this. so its not vacuum leaks, but can be stuck closed ISC valve, staving idle air. sure.
usa answers not export.
Tune up, air filter, fuel filter? When was the last time?
Badidle could be a vacuum leak egr valve stuck on idle air conttol
