My KL has developed some type of idle problem and I noticed that this thread seems timely and relevant!
When pulling up and sitting at idle the engine will suddenly choke for a second or two and then die out.
Theres no warning and no engine light.
It restarts perfectly.
I've tried to find a pattern but it only seems to happen at idle and only sometimes, not every time I drive it.
Otherwise its rock solid. And I do mean rock solid, excellent idle, acceleration and otherwise fine.

I put some injector cleaner in last week and its been driven about a hundred k's since but it happened again yesterday.
Its happening often enough to be an issue. I will organise to take it to Mal but if anyones got any ideas based on my description, please let me know.

Only things done recently are oil change and a battery change.
