2009 Jeep Lib Speedometer Stops, Stalls and LIghts come on

no , you were told wrong, but ABS is bad too. (or was just the stall resetting ABS to self test mode)
you have 2 independent failures.
1: brakes. (if ABS is on,, not stalled !!!)
2: engine. (this is IT, fix this)

you are guessing at ABS parts.? just throwing them. why do that?
my guess is you have a mech, and you want seconded guessing
on line with blind folks here.

the engine stalls moving,
that usually means the ASD relay dropped out, did the IMMO light come on? you need to look at what all lights did in the cluster at stall.
a stall causes rapid deceleration and loss of all engine power
and RPM drops and MPH drops and at the point of stall
all Cluster lamps go ON. they go to key on self test mode as
stated in the users manual. (lost sure)
to witness this, key on, no start, and bingo the self test happens.
those are NOT failures. its just a self test. Per manual.

Does the ABS stay off driving and not stalling or stalled.
yes, then ABS is ok......

did you take it to a shop (crooks) and tell them my ABS is on?
and they see it's out, and go, gee we can make some cash here for nothing. if you tell them wrong, they will in fact guess, and make you broke fast.
ABS can go on just with a bad brake caliper pad. a $10 part.
if car stops ok, and the lamp is out RUNNING !!!!
Then leave the ABS alone. why assume the most expensive part on car is bad, why do that...???? why not put on new pads. and rotors.
first. then test the ABS. ABS is not magic it cant help stop any car with bad manual brakes. not at all.
end brakes; now back to ENGINE.

then fix the stalls,
here is the stalls list, for only the ASD.
(even a tuneup, will end stalling)

THE ASD is the funky Jeep thing, that kills the engine for many a reason. (there are tests for each case failure)

if the CEL lamp comes on driving < NOT STALLED)
then connect any scan tool, to the DLC connector at knees.
and scan the PCM for DTC errors.
then post those.
keep in mind, errors can AUTO clear, so not seeing them
in REAL TIME< means you missed the boat.
that is, you didnt get the facts of the failure.
but errors still in effect are stored and you can in fact
scan them parked, key on.
the CEL is only a SMOG light, you must scan to see the other 100+ errors. possible.

find a real ASE shop, and ask them to fix the stalls, (car stops good)
then they will fix that
and by magic the stalls are gone and the dash lamps go happy.

I have a yellow light on my dashboard, resembling an engine that has suddenly come on. What does this (could this) mean? I drive a Jeep Cherokee 2004 3.7L. I am in South Africa, but I believe what we call...

I think I can help here. This is the check engine light and in order to find out what is wrong you will need to get a hold of a scan tool. Theses typically look like this:

That tool hook ups to a small connector just under the dash in the drivers area. Follow the on screen directions to retreive/read trouble codes. Write down what all the codes are and get back to me and I can tell you what to fix to get that light off. You can also clear the codes with that tool but if you dont fix what is wrong then the light will some back on.

That means that your computer has detected a problem with the vehicle. Take the car to Autozone and they will scan it. It doesn't cost anything. They will tell you the problem and what you need to fix it. Get it checked asap just in case so it don't get no worse. If you need anything, let me know. I am here to help. Thank you very much for using FixYa.

Svc engine light keeps coming and engine races. replaced gas cap ran fine for 3 hours

If your light is on, take it to Autozone. They will scan it and tell you what is wrong. It is free. This will let you know what to check. It could be a few things, but with a code, you will know for sure. I don;t want you to waste your your money for nothing. Autozone will tell you what the code is. It could be a MAP sensor but that is just one possibility. If you need anything else, feel free to contact me, I am here to help you in anyway I can. Thank you for choosing FixYa.

How to turn of a check engine light after oil change in a jeep liberty 2006

Changing your oil has nothing to do with the engine light, if your check engine light is on then theres a problem, the computer stores codes when it sees a problem with the engine not operating correctly, you may not notice anything strange but something is wrong, the codes help in finding the problem, for example the code is po236 coolant sensor circuit. this would mean theres a problem with the circuit for that sensor and with some testing the problem can be repaired, you can go to a autopart store and they will scan the codes and give you a readout of the codes if you give me the code or codes i will be able to help you more, the engine light is reset with a scan tool or leaving the battery unhookedfor about 10 min,, the engine light will come back on when the computer sees the problem during its constant testing of all systems. hope this is helpful.

Engine light on 2007 jeep liberty

This light could be on for many reasons, this light comes on when the computer sees the engine is not running right or sensor reading is out of specs, you will need to have the computer scanned for codes, these codes will tell you in which system the problem is in, sometimes it can tell you very close to what the problem is, a loose gas cap can make this light light up or a faulty sensor or bad sparkplug and on and on, so start with the scan, autozone the auto parts store and others will scan the computer and give you a print out of the codes, for example a po301 code, if you get the codes i can help you find the problem, hope this helps.

I have a 2001 Jeep GCL with 125K miles. Engine Light has been on for a few months. Jeep is running great. Any ideas what might be wrong?

have a code scan done (most larger parts outlets do that free) likely you have a bad O2 sensor but without testing, it really could be just about anything.
