Alfa 156 1.8 TS 16v bosch M 1.5.5 reset and learning autoadattativi engine idling

[special]

Here is the procedure that I have done to solve the problem of the minimum-sawing on the alfa 156 1.8 ts 144cv year 1998 (with natural gas)

RESET PARAMETERS AUTO-ADAPTIVE MOTOR STEP-BY-STEP MINIMUM:

1? place the ignition key in the on position, ignition on engine off
2? disconnect the connector flow meter and leave it disconnected
3? disconnect the connector coolant temperature sensor and hold it in your hand
4? with a wire or a paper clip wire to short circuit the two contacts of the connector to the temperature of liquid for about 1 second then remove the bridge, you hear? the stepping motors humming
5? wait approximately 1 minute
6? turn off the ignition and remove the key
7? wait at least 30 seconds
8? reconnect the connectors loose in the above flow meter, temperature sensor
9? insert the key and turn on the car to bring the temperature of the engine and proceed with the learning of the parameters are self-adaptive.

LEARNING PARAMETERS AUTO-ADAPTIVE STEPPER MOTOR MINIMUM

the procedure should be performed with the engine at operating temperature and climate turned off, then repeat the procedure with climate inserted.

1? veico idle with the engine at idle with methane fuel (temperature liqido above 80?)
2? every 40/45 seconds to give a flick of the throttle to 3000 rpm and then wait again 40/45 seconds and re-accelerate up to 300 rpm
3? usually need 4/5 cycles to stabilize the minimum
4? repeat the procedure with the climate entered ( the climate must be adjusted at an average temperature, not the maximum of its capacity? the refrigerant)

a greeting to all I hope it will come in handy with the procedure

without all of these steps with self-before the gates errors and then have the rest of the parameters . after the framework on 1 minute then the framework off 1 minute of the new framework on 15 seconds and then start the mot. at idle for 5 minutes without touching the pedals and accessories switched off.

also tried with a diagnosis of both autocom and with the *********** but the problem persisted a minimum very fluctuating, however after this procedure ? became much more? stable.

usa diagnostic serious...***** o if you ricapita do the procedure that I have suggested (without attacking) diagnostic and you'll see that acts as a..the same

some time ago I read on the forum that alfa even of the examiner were able to reset the parameters auto-adaptive
