Rough Idle at Startup

[Mindthegap]

Hi,

I picked up a used Lexus 450RX on Wednesday which is approved used.

It is a 2013 model with 66000 miles.

Both mornings when starting from cold there has been a judder and a slight knock for a few seconds and then settles down again. Have had a quick google and seems like this is not an uncommon problem. Some people reporting injectors being replaced, others saying it has happened for a couple of days after an oil change (Oil was changed the day before I picked the car up). Anyone any ideas on this?

Thanks

Take it straight back Jeff.

Unfortunately it is 4 hours away but just on the phone to them now to see what they can do.

Who are "they" and tell them that you wish to take it to your local Lexus Dealer Jeff.

Car is booked in with local dealer for the new year to keep car overnight and then they can test the following morning.
