Car Stalling

[tabletennisman]

Recently we've been having a few problems with our auto AU1 Futura. It all started with the car not starting making a tick tick tick sound as we tried to start the car. All the lights, etc inside the car worked, but just wouldn't crank over. We soon discovered it was the battery so charged it up and the car started fine.

But here was where the problems started. The car sometimes stalls when below 500rpm (ie when stopped at lights or going very slowly). I've noticed when it "almost" stalls (car shakes), its at around 400rpm, and its fine at around 550+rpm. So, I've done the ECU Reset, and have since done just under 300kms, but are still having the same stalling problems. All sparkplugs have been changed as well as new oil, oil filter and air filter.

Anybody have any ideas before we take it to a mechanic?

Cheers, Appreciate any help!
Adrian.

EDIT: It only struggles when in drive/reverse. Its fine in neutral and park.
