idle make me crazy, please help!

[jtjerry]

hi
I have idle problem.
Wheh hot, idle drop to about 800 next 500 and stall and die oftem. That su** especially when drive to the lights and must clutch engage, when it stall and die. sometimes it back from 500 to 1200-1300 and next 500 again and die -or not- as that stupid car want...
what I done:
checkng leaks (100 times: nothing)
cleaned GOOD TB 4 times: nothing
change step motor (nothing)
checking coils resistance at step motor: always 28-30 ohms always nothing
change o-rings on TB shaft (nothing)
adjusting idle (100 times: nothing)
adjusting SAS (100 times: nothing)
adjusting TPS 10 times: nothing
reseting that stupid mitsu car 100 times: and nothing...
changed for temporary injectors,
changing spark plugd several times,
changing spark plug gap,
changing two times spark plug wires.

now I cheating that bi*** by screwning SAS as much as it open slighty TB plate so now idle are 1000-900 and at crusing when press clutch not stall and keep 1300 RPM.
But that is not normal conditions. Any advice? that idles make me crazy...Thanks

settings in translator are basically stock: all on zero (tomorrow will dyno and tuneit with wide band). Only idle is -2. at thah position do not run extemly rich as on zero.

there is another strange thing
at translator manual (I have 2.00 ver) is that green LED should be off at idle but in my translator it is dim as should be in cruse not on idle...

problem solved!
that was timing belt. After time belt change (I was done that when buy engine) mechanics put it wrong (two teeths on exhaust and two teeths on intake). So all the time since I have that car (one year!!!) I was riding on that crap timing.
Now there idle is ok. Must set timing tomorrow.
