Hey guys just wondering if anyone can help

My wifes au2 has severe drop in revs when we come off throttle into a corner. it drops low enough make steering heavy.

any tips would be great.

I'd check/clean the IAC/ISC valve, and also the power steering switch. mine was doing the same thing, stalled a couple of time... i just cleaned the whole throttle body and isc valve with carby/throttle body cleaner... working fine now...

is the AU Auto or Manual? mines manual but iv head of issues with the auto clutch not disengaging in time?

depending on the system installed, the balance line might of been disconnected

ours would do it only turning left.
mixtures were not right.

i spent the weekend with gas ECU disabled and a wideband O2 sensor fitted.
Adjusted everything to have the mixtures as close to perfect as i could, that way when the ECU was reconnected it had only small adjustments to make.
fixed the stalling, fixed the backfire, and netted me and extra 80km to a tank.
Also found out that it goes lean at revs and could not be made richer.
