Take a piece of plastic bag and block AUX air valve hose. If it doesn't help, do the same for brake vacum hose. If neither one helps, it can be electrical. Check timing for "walking". Check distributor mech advance springs. If that doesn't help. it's time to find an air leak. Spray Start Gas to intake manifold, FI injectors and so on. If idle jumps, you found it! If you don't know what to do nxt, find someone with same year car, in good condition, and start swapping parts untill you find the bad one. Finally; If nothing helps, send me a plain ticket, I'll come and tune/repair it (I'm ready for vacation). Don't do SU conversion! FI is superior and your problem is not usual.
