There are several things that could be causing this problem, from a bad spark plug, igntion wires, distrubtor cap, injection , no compression in that cylinder. Try the simple things first = plugs, wires, cap etc. a bad note: these are known to have the injector "poppets" fail with no warning. Go there when all else fails. good luck.

If someone said the freon is leaking out, then you have a leak that needs to be repaired. Every connection in an AC system has a seal. AC systems work under very high pressures. When a seal goes bad, all the freon in the world will not stay in.
They sell kits with all the seals just for this purpose. I'm in AZ, so I can't help you. Plus, I'm working on the AC system in my wife's car right now. What you need is a reputable shop that can do the work for you. The whole system needs to be gone through. It will cost money to get it done correctly. And you should have a professional do it, not some shade tree mechanic. Good luck. I know what east coast summers are like.
Sorry I don't have a better answer.

P0452 is related to the Evaporative Emissions Control system and has nothing to do with the 4WD system.
The P0452 may be something as simple as a loose or bad gas cap.
The 4WD system is somewhat complicated and requires more diagnostics.

I guess my first question would be are you sure you got the right replacement belt ? And are all of the pulleys on straight ?
Is the belt slipping, or coming off ?
Was the original belt giving you problems ?

Hello: The best to do is have the system checked with a scanner to get the code but most likely you have a pass-lock system problem. The whole lock cylinder will have to be replaced along with a new key.
