idle speed: 750 rpm w/no electrical load, 850 rpm with E/L
idle afr: dont know (ECU controlled) (won't presence of air pump circuitry change this too?)
idle vacuum: 17inhg most of time, up to 19 during warm up rpms @1000
porting: stock
intercooler:stock
turbo type: stock twins, ~ 50K miles
ecu: '93 stock

Note: my idle WAS hunting and dying with electrical load on and placing car in gear. Would fluctuate from 750 to ~250 a couple times, then die. Would stop fluctuating if I took it out of gear OR turned off electrical load (ones that affect the E/L sensor). Replacement of clutch switch (the one on top of the clutch pedal, not behind it, which is starter interlock) fixed most of the hunt, replacing the neutral switch on the tranny made it rock solid. Changing the 1-2 switch (manual trans) did nothing to help idle problem...

Note also: After idling for long periods of time it flucuates between 150 and 1500. Plus if I have to stop right after getting off of the freeway it kills.

My car has 2 distinct idles. I'm doing a full vacuum hose job to try to fix it (I'm guessing it's a vacuum leak somewhere.

idle speed: 1100 rpm
Idle afr: unknown
Idle vacuum: 17+ in/hg
Intercooler: stock
porting: stock
Turbos: stock twins
ecu: stock '93

idle speed: <500 rpm
Idle afr: unknown
Idle vacuum: 12 in/hg
Intercooler: stock
porting: stock
Turbos: stock twins
ecu: stock '93

One thing that I've noticed is that my idle vacuum is directly correlated with the idle speed. At the 1100 rpm, the vacuum bobs between 17-19 in/hg vacuum. When the idle drops, the vacuum does too. Around 16 in/hg at 1000 rpm, 15 in/hg around 750 rpm, and finally 12 in/hg when the idle settles sub 500 rpm. BTW, the idle doesn't hunt at all, there's a definite high and a definite low, which randomly seems to occur. BTW, this is on a car with 104+k miles on it's original engine.
