Sounds like an intermittent miss. Possible worn plug, bad wire, or an injector that is shorting out. Check to see if any codes are set. This will help you narrow the problem to a certain cylinder.

normal for an engine to start at elevated rpm and then die back as it takes a few seconds for the ECM doing it's sensor checks and idle back to the correct idle speed
check the idle rpm with an external rpm counter as most in dash units are inaccurate at rpm lower than 1000
as for the temperature
If you have a climate control module, it uses a mixture of heater and ac to maintain the temperature that you have set
so check it for operation

NEVER NEVER USE BELT DRESSING. It's sticky and attracts grit that destroys your pulleys. Screeching is almost always caused by a worn belt tensioner. Read these posts

access mode using an incorrect PIN, secured
access mode will be locked out for one hour. To
exit this lockout mode, turn the ignition switch to
the ON position for one hour, then enter the correct
PIN. (Ensure all accessories are turned off. Also
monitor the battery state and connect a battery
charger if necessary).

There is a safety switch on the brake pedal and if it fails you cannot move the gear shift lever. Check under the dash on the brake pedal shaft for the switch and make sure it is not loose, disconnected, damaged or failed.

ok , if you open the book called FSM(its free, despite above)
what do you see, lots
whole chapter on cluster.
and better a chapter 8w (wiring)
just sold my wrangler 02 and upgraded to 08, (a bad idea) xxxxxxx
step by step.
click TJ here ,then o2 (see link below)
posted this answer 100+ times here...
first my guess fuse blown or bad ground
do the park lamps glow in cluster? (bet yes)
only warnings out, and parks glow in park mode?????????
page 2
fuse PDC 24 blown
fuse FB 10 blown (fuses can look ok, and not be good ,a fact)
ground g201 cut? ( see link below )

this is a computer based cluster, and all data is sent to it via
a network, (unlike cars of old) PCI network.

we scan it first. a the OBD2 port, PCM
and if you see errors on the PCI NETWORK ,BINGO


the cluster has a self test mode, (ask) but does not prove
it can talk to the PCM etc.
the non computer warnings (i call them direct drive )are"

  1. ABS
  2. brake warn, and hand brake lamp
  3. park lamps (aka, illum)
  4. Turns (look ma, no blasted computer here)

now you know how the IP cluster basics work

the free book, unlike spam bs above. is here

to answers 100% accurately id have to drive it.

but here in net bunny land, cant do that!
but can ask you to post full symptoms.

(trans or clutch issues)
question 1: can you start car in any gear. clutch held to floor, even reverse )
Q2: once started, can you always shift to reverse (the tricky one, gin?) and not grinding and no complaints,balking?
yes then your transmission fluid is low.
or worse.
is the clutch MC full? and does not drop day by dead week by week???

q4: new clutch
all 5 parts? or more?
PP pressure plate
throw out bearing
flywheel pilot bearing (oops?)
new slave cylinder? ,mc set

the slave and mc are a fixed pair in 2002.FSM C6-p9
and on my 2008

the slave and MC are one part and pre filled.
there is no bleeding steps only top offs.

if the clutch drags,(seems it does)
put in a new MS/SLAVE first.
avoid the 10hr labor. if a new clutch, 4wd.ad4f429a-1dc7-4f8b-aa26-1116f5bce673.jpg

I have lots more to ask.
trouble putting
so you are driving
and shifting and moving
and 1>2 shifts are what, grinds, or balks.

can you start engine in any gear (clutch to floor)

can you shift any gear parked ,running, and clutch to floor and not moving. including REVERSE ?
if all are good, cept the 1>2 upshift
that means the clutch is not dragging.
and the #2 synchro ring is worn.
or running the wrong trans fluids.

the newer transmissions are very tricky here.
some are very upset with wrong lube. (or too low or is not black as tar)
or mixing 2 brands, or using synthetic and its so slippery the syncrho fails, (cured many like this)

if all this is true, and clutch don't drag (ever)
then get the car to jeep and have them drain it and fill it with the correct lube and win.

now answer 3:
it might be just the shift linkage messed up
if the 1>2 change balks. (not grind)
on mine boxes i can hear the synchro's spin up.
i can feel them engage, if i cant feel that
then the linkage is bad.

the word trouble does not say what that means.
define trouble putting....

find a shop, a Service tech, that owns a m/T box.
and win.
Some with a/t are clueless...
ive blown more clutches racing than many ever drove.
IMO, and remember it COST YOU NOTHING to ask. (I'm retired early, gin!)

2002 Jeep... | Answered on Aug 22, 2015

first off it only gets out 1/3 of the fluid by hand.
you know that fact right? putting fresh atf over mostly old is a wasted effort. right, unless done 3 time in row>?

.i guess you lost the operators guided, or cant google search this?

a full flush and filter works best. any ASE shop can do it.

on a station, (regardless of sound or not) if not ? all that is dea check fuses.
