rx300;lexus Hi All, newbie here * Issues with my 2005 LEXUS RX300

[simplelearning]

Hi all, got an issue with my RX300. I had the dreaded error codes come up for knock sensors. I got them changed and the error codes disappeared. Now for some reason the car starts up but just cuts out after a couple of minutes. There are no error codes. Could it be the idle control valve as thats what comes up on the internet as a possible issue? Also isnt the ICV electronic and would error codes up come? Thanks in advance

Hello and welcome to the LOC.

Do you have any new fault codes that have appeared?

Also does the engine restart immediately once it has stopped or does it then fail to start after completely?

Hi, it restarts with acceleration. I took it for a spin to check it out. On a normal run it drives fine but when braking it and coming to a stop it cuts out. It cut out when attempting a 3 point turn. 

No error codes at all.

Someone said it could be the idle air control valve, does this seem right?
