Hi, see my post re blocked MAF. Sounds as though your problem is very similar. Regards Trevor.

Hi, sounds very similar to the problem i had, car went ok above 2000 revs but flat below that. Problem was traced to the MAF valve and car has been ok since this, and the EGR valve, were cleaned by Lexus Nottingham. I did subequently put a can of Bg244 in the tank and the car does seem to be a lot better since this. Returned some 51+mpg on a round trip of 250 miles, smoother running and good low down torque, so quite impressed. Hope this helps.

Thanks for reply Steve. Strangely car did not have any warning lights and was not in limp home mode. Ran OK once revs were above 2K, just a bit frightening when trying to pull away.

Hi everyone, have owned my 07 IS220D, 78K miles, for some 18 months and have noticed a distinct lack of power when pulling away from traffic lights, roundabouts etc. Read forum re EGR valve and, as vehicle was due a service, took it to Lexus Nottingham. After a lot of work, including cleaning the EGR valve and checking the cat for blockage, the fault was traced to the MAF sensor, (whatever that is)! Don't know if anyone has had this problem but worth noting perhaps. Cannot praise Lexus Nottingham highly enough, very good service and they only charged me for 2 hours labour when I suspect that finding the fault took a lot longer. Have no hesitation in recommending them if anyone in the Nottingham area needs work done.

Hi everybody, joined the club today and found you whilst trying to find a reason why my 07 IS220D has a massive flat spot at low revs. From your posts it seems that the EGR valve could be full of carbon and requires cleaning. Lots of information available and am very grateful for all the advice so promptly joined the Club.
