check your CV joint

I assume this 'complete' tune up was plugs, wires and plennum (intake surge tank) gasket?
If so, recommend you first check to see if you are getting an injector pulse to the #3 injector (a noid light is normally used to verify the injector is receiving the 'pulse' from the ECM. The noid light is a very useful tool in finding out if you have problems with your fuel injector. It is cheap (around 10 dollars per piece), easy to use (if the light blinks, your injector is receiving the electrical pulse to open). If after you verify the injector pulse is present, the next step is to determine if the injector or cylinder is the problem. A simple verification process requires swapping the #3 injector with another to see if the misfire moves to the swapped cylinder.(.i.e, move #3 injector to #2 cylinder & the #2 injector to #3 cylinder.).. Then run engine to see if the P0303 changes to P0302. This would VERIFY the injector is in some way defective. If the misfire STAYS at #3 cylinder, you'll want to perform a compression test of all the cylinders. If after this test you find #3 cylinder is more than 10% lower than all the other cylinders, do a 'Leak-Down' test to determine if the low compression is due to leaky valves (intake or exhaust) or whether the piston/rings are the problem. NOTE: If all the cylinders are withing 10% of each other during the compression test, the possible causes are, injector O-ring leak, vacuum leak at the intake manifold at #3 cylinder, or the spark plug not firing under compression.

there are two hoses that usually 20 to 25 mm thick that goes from manifold to you engine fire wall , before they reach fire wall you will see a silver can shaped object with a linkage attached , replace this unit. by removing hose clamps , you should see a choke type plate inside that is jammed or broken , usually closed which what stops hot water going through you heaters .

should have sticker on radiator showing routing

I have an 2005 2.7 L engine and when it was doing that and stalling I had to replace the coil packs.

Sounds like your alternator is failing. Check voltage at battery while running. Should be close to 14v if 12 or under you will most likely need to replace it

Goodluck trying to find one to download on the internet! I've been trying myself for my 98 Sonata & no luck at all!

check low press switch

get the manual at emanualonline.com for 9.99 pound

It is inside the fuel tank

easy to check. open hood and count how many spark plug leads come from the engine block. 4 leads = 4cyl 6 leads = 6cyl

The problem with what you have done is to introduce faults into the ac system. The ac may have stopped working from over or under pressure in the system in which case the ac compressor would stop working. There is a very fine tube in the evaporator that is easily blocked and will not allow the gas to pass from liquid to gas and so cool the car. I suppose you checked for power to the compressor clutch before you touched anything as it may be a faulty ac switch or fuse.. If you put antifreeze in the ac system then you are up for a complete system as the glycol will destroy all the internals

your computer is f*cked
