I have seen jeep TPS - throttle position sensors cause a surge like you describe , but not with injector circuit code's . The PCM - engine computer controls the injectors by supplying a PWM - pulse width modulation ground . Checking the electrical circuits for those injector's would be the thing to do . Do you know how to test electrical circuit's ? Plus checking the drivers (transistors ) inside the PCM should be done . Could be a wiring or computer problem or even those injectors could be failing .

Take some lube spray and spray the entire lock assemblies. You may need to take the door panels off to do a good job. With the panels off you can watch and see what is happening.

Rather then guessing an just replacing parts , have a qualified repair shop hook up A/C manifold gauges an check the system . Can tell you what's wrong in just min.
(it is only blowing slightly cool air. I suspect it is the orifice/expansion tube and want to know if I can change it out myself or reair it.)
Don't suspect , that's guessing . test don't guess . Are the A/C pipes going in through the fire wall cold ,have ice on them when A/C is on ?

I would say the alternator. The fluctuations when it is running indicate that the regulator inside the alternator is worn out. The overheating is probably because the cooling fan is not running fast enough or at all.

Your only problem friend, is the temperature sending unit/sensor. Upon cold start, this sensor wil tell the computer to go into cold start mode putting a bit more fuel in and raising the idle a bit to keep it running when cold without using the throttle. Replace that sensor and your good to go. Makes sense, right?

back firing ( explosions in the exhaust) can be from fuel mixture too rich and unburnt fuel is getting to the hot exhaust
possible causes for that are excessive fuel pressure , leaking injectors ,leaking injector seals
backfiring through the inlet manifold can be calve timing, ---cam advance servo-- valve staying open ---valve clearance , problem hydraulic cam follower , incorrect firing order for the plug wires, crank/cam position sensors or wiring

You probably have a poor earth on a rear light cluster, if you can find the earth wire ( often goes to the body close to the lamp) that will be the problem and it will need cleaning or a new terminal putting on.

Stop leak can cause the radiator ports to get clogged. But if your car isn't getting heat, it's probably your heater core. The heater core is usually burried in the firewall between the engine and where you or your passenger put your feet

not sure what type vehicle we're talking about here, although you can lube up the rack and pinion or grease up your upper, if so equipped, and lower ball joints.

when did it make the clicking. was it when turning sharp, if not it is another issue

it could be a problem with the wiring with the sensor. You would need a multi-meter to check the wiring. Diagnostics cannot tell if the sensor is bad, only that the information sent does not agree with what should be reported.

I would take it to the shop that did the repairs and take them for a ride and let them know it started after the repaired the brakes.

Hello Faye Sims,

Whatever you are looking for... it is big & common
to a lot of circuits... My best advise when starting
to trouble-shoot MULTIPLE ISSUES is a start
at the MAIN BATTERY & GROUND connections.

(unless your CHEROKEE has recently been flooded).

Start at your battery posts and move METHODICALLY
through your main body (ground) & Starter cables
(battery) and make sure the connections are clean
and tight.

Look for corrosion, breaks or discoloration of insulation or any signs of heat... Unless you are in a terrible rush... Shop for best prices from reputable sources (Like: Rockauto, Napa,
even eBay & AMAZON (etc.))... also such products as
CONTACT CLEANER, NALOX/NoCo & battery washers
(in my opinion... are a MUST on AUTO-BATTERY posts).

See here:
Amazon com Battery Anti Corrosion Washers 2 Red 2 Black Automotive

Quality High IMPEDANCE (or No Contact) VOLTAGE
TESTERS... will protect existing circuits while attempting to find faults... (without FEAR of triggering EXPLODING AIR BAGS
(in my opinion))... Or destroying semiconductors w/ spark...
Klein Tools NCVT 2 Dual Range Non Contact Voltage Tester Amazon com

Amazon battery cable
Amazon com Deka 00297 Positive Battery Cable Automotive

Rockauto battery cable (less $, 3 years, 36000 miles),2000,grand+cherokee,4.7l+v8,1381418,electrical,battery+cable,2500

Finally... Check out buying A FUSE at your local parts store
(abusive & egregious $$$$ (know your FUSE TYPES))
Amazon com Bussmann NO 44 ATC Blade Fuse Tester Puller Kit Automotive

Comment me back... Spent a lifetime doing this...
(love it)

Didn't notice which Jeep model/year you have but if it didn't have those issues before, make sure you don't put the filter on backwards.
