My 92 fastback has a problem with idle it doesn't go below 1500rpm I disconnect the idle becuz when I connect it and drive..the car turns off when I step on clutch..and my speedo meter also show 10mph ahead
It's stock injectors , stock ecu with garett GT2871R

did you try adjusting the idle air control valve (IACV) ?

you can turn down your idle with that.
