So some information on the car before I state the problem.

She's a stock 96 GXE automagic with 234k miles on it, and this problem
has just recently begun (started 2 days ago).

Problems:
- Lower Radiator hose is swollen
- Left Bank 02 sensor needs to be replaced
- Coilpack 2 has dried oil in it, but worst of all coolant
(fresh) at the bottom of the coilpack

Did the checks to make sure coilpack 2 is done for and yes its dead.

So the car bucks when i turn on the ac, and also bucks while in
drive, but the car's temperature never goes above the middle
of the gauge.

it only bucks for a while, once above 1/4 on the temp gauge,
the motor stops bucking.

My question is, does this mean that my motor is telling me it's
about to check out to motor heaven, or if i replace the lower
radiator hose, that it will stop the coolant from leaking into
coilpack number 2.

I'll take pictures, and did i mention the car is stock.
Any help would be appreciated, i also have the opportunity to go
DEK, if the motor is doomed

 

Coolant in 2nd coil pack? Was that spilled there? If that hose is swollen, you had better get it replaced before you get stranded where you not suppose to be. Replace the defective coil pack also and report back. Check the oil for milky texture.

 

With those symptoms I would:

1. Replace both upper and lower radiator hoses, replace coolant, thermostat, and temp sensor, just to give your entire cooling system a proper maintenance.

2. Replace O2 sensor.

3. Replace that coilpack only. Stick with Nissan, even a used Nissan coilpack from junkyard that is good.

4. Replace both valve cover gaskets to fix the oil leak.

I think the coolant spill is an outlier because cylinder # 2 is close to the coolant over flow, radiator cap etc. Some coolant may have escaped from those spots. If that's not where the coolant came from, then you need head gaskets, but let's not think about that right now
