Well, the problem is that I have no real facilities to do a thorough inspection (the college parking lot isn't the best choice), but what i've looked at so far says:

the air filter is clean and un-obstructed

the fuel filter, to the naked eye, appears to be in good condition (Can't get far enough under the car to get it off)

spark plugs are a real pain in the a$$ to get at, You would have to remove the coolant res and possibly the dog bones to get at them well, I pulled the coolant res and disconnected the wires: connections all appear to be clean and not corroded.

Nothing appears to be leaking from the tank, or fuel anywhere (just about everything else on that car does leak)

the exhaust has been replaced from the cat back, but it is the original cat and it appears to have some pretty significant rust damage.

Thats about all I can check into with basic tools and no lift.
