Hi Fredric,
I did my servicing from Al Nahda Auto, Ras al khor.
Actually there was one more issue (which I didn't mention b4) - after the injector cleaning & Spark plug repl. -> I started getting a slight delay in starting the engine from cold - that is, the engine cranked 2-4 seconds extra, before switching on. But this happened only when the car was resting for 12 hrs/overnight (not during when car was switched on, when it was in use). When I went to them a third time, yesterday, they cleaned fuel injector again -> & the delayed start problem went away (though it has only been a day)
Regarding the error code -> I didnt catch what it was (that was stupid of me)
I dont want to go back to them again - as they seem a bit clueless. (I am not sure if u are allowed but) if you can advise an alternate garage for me, that would be great (you can whatapp me on+971 502949628)
Also, I did some research - from the below video, it seems, this is a common issue in toyota/lexus - because of faulty fuel cap - https://www.youtube.com/watch?v=DgUvPQg310E&ab_channel=TheDocMackCarChannel
Let me know what you think.
Thanks.
