So my 1988 wagon (love it!) slowly started having issues. It seemed at first to be experienceing a low idle or slow ignition. Now, a few weeks later, it dies at intersections or anytime I put in the clutch. Even after my hour commute. It was a slow process. I took off the air filter lid and saw that the little tube (air intake?) was full of gunk, so I am thinking it is messing up somewhere in the oxygen/fuel mix. Any ways for me to figure this out?

Possibly a fuel issue, but have the pressure checked before condemning the pump. Is the gas filter good? And the air filter?
It could be an idling issue-idle too low. Check if can be raised, or if idle control motor or valve needs service. Idle should be around 750 rpm, in drive gear, maybe a bit lower, not below 650 rpm, though.
There are many things that could cause this problem,a misfiring cylinder ,low compression or idle speed not adjusted right, Is this car fuel injected or does it have a carburetor? if the timing is off, or the main problems i have seen are in the carburetor. does this car have an o2 sensor? a bad o2 can cause a bad fuel mixture and make engine load up at low idle speeds. this car is a 1988 Camaro, what size engine , automatic or stick and is it carb or injection fuel?
you need to have the fault code pulled to see what is acting up. you can throw alot of time and money into a vehicle by swapping parts. from the problem you desribed it sounds as if the o2 sensor is slow to switch and cuasing fuel control problems.
Because it's carbeurated they have an electric 'idle up' solinoid (or vacuume) to compensate for rev loss when load is put on the engine caused by the alternator working harder because your using power. It should have a small adjustment screw on the carbeurator to lower the revs. If you have it set too low it will shudder when in drive & foot on brake with headlights on. It should only pick up about 200rpm when lights are on. To find the screw, take the air filter off, run the engine & look for something moving when the lights are turned on & off. Somewhere near the moving bit you will find the adjustment screw. I hope. I'm not sure exactly where it is on that model.
If there is two batteryes,make sure they are eakal charged and keep same 1,28 in liqued. One new and one old sertain worn out the good one.
Check ignition when charged battery,if not you migth have to low voltage for the electronic to work
