My 1992 jeep laredo is stalling out but it will start back up but will not stay running and it is pulling codes 23/41/62 up

yes
sure
XJ jeep, USA? or ? where?
NO VIN OR ENGINE TOLD AND IS A PURE ENGINE QUESTION. 4.0LITER INLINE SIX>? or 2.5?
SURE MY JEEPS DID THIS VAST TIMES FROM, 1988 TO NOW. (WELL NOT MY 2010 EVER)
back back long ago he ISC clogs up ever, 10,000 miles
and will not idle ,lacking the IDLE AIR SUPPLY
world wide 10 engines were used XJ. sorry facts.
in USA 17 digit VIN the 8th digit is engine code.
or post photo of engine and i tell you whats under the hood.
worst ever mistake is selling my 99' last good jeep made. IMO. (minimum of computers)
1992 here is 4.0 L AMC 242
or the diesel but is 94 to 02.
so is 4.0 only if in USA. or 2.5L (cut down 6 to 4)
owned 3 Cherokees with 4.0 drove em, 1/2 million miles, and did all the work.
ONLY FAILURES WERE ISC.! best cars ever owned 1965 to now.
repeats
what I did is use magicGUN lube on the ISC
off 'd the ISC
and with super special, gun lube spray for guns used in SIBERIA, "dry lube", looks like black teflon
after it dries, on the ISC cone i spray.
and now ISC goes 2 or 3 times father.

in truth the ISC is weak
later they went to motor drive and ended this pain.
solenoid drive fails. &sticks.

ISC= idle speed controller (or IAC)
here it is. clean it and drive
vacuum leaks cause racing engine and full power
so is not leaks.vac. 2.5L same. deal

An easy test to see if the alternator Is charging, is to place a paper clip against the rear bearing cup (the back of the alternator case in the center) While the engine is running, the paper clip will be attracted to the bearing if the alternator is good. Do not short the paper clip to any wire terminals to avoid a burn hazard. Be careful of rotating belt and pulleys.

run fault codes and check for MAF/MAP and VAF sensor problems

If it's been sitting a while it's always a good idea to put some sort of gas treatment in it. Ethanol added to gas nowadays is bad about getting water in it if it sets.

i would see if you have a friend with a code reader that will plug into the obd2 port to read the computer. it sounds like the computer was trying to run a self diagnosis program which shouldt happen unprompted.

Does the vehicle crank for extended period of time upon first starting? If so the fuel pump needs replacing.

is it diesel engine?if so chech ur heater plugs

If it started when you changed everything, make sure the cap is tight, plugs are gapped correctly, wires are in right spot.

i had the same problem. i replaced sensor after sensor and it kept stalling. i finally replaced the crankshaft position sensor and it's been running strong since. i have a 1996 jeep grand cherokee laredo so i hope that this will help!!
