E30 Track Kar

[ispoonwithmugen]

Okay so I have it "narrowed" down to these:
Vacuum leak
Clogged injectors or bad wiring
Idle air stabilizer valve (hoses as well)
Coolant temp switch and sensor
Large intake air duct
Small hose between intake manifold and pressure regulator
O ring on injectors
Ignition and distributor cap
Grounds
02 sensor? I was thinking I could rule that out since it won't kick in till the car is at normal temps.

Any thoughts on these? Can I eliminate anything or should I include some other things?
