Hi guys Little update. I used BG244 2x cans over 2 full tanks of fuel on my trips to airport. That loss of power seems to be no longer an issue. However i still have that erretic idle when hot. The engine runs perfectly over 200 miles on motorway i've been reving it from 2k to 4.5k revs and it is just perfect no issues no nothing than after that jurney I'm waiting for lights to go green and i've got those revs to go up and down and engine is experiencing intermittent stalling, it just shuts down. But guess what, no error code, and sometimes it shows low fuel pressure but it should not be an issue cuz when on motorway it goes up 5k revs and no issues. I got few things to check Like: Fuel filter housing (on last service they broke it and glued it together .... but they did not mention it to me .... just saw it when had my car on the ramp) Fuel pressure sensor. Vacuum leak Ignition timing may be set wrong Idle speed set incorrectly Fuel pressure regulator I will try to make another update whenever i eliminate anything or get it sorted... But if you got any other suggestions please leave a comment Thanks Arthur

Hi Unfortunetly I'm still having that erratic idle. I bought BG244 and i will use it in a week time when i will run a trip to an airport (300 miles) and i will update you guys if that helped.

Fuel Filter was changed on it's last service and that erratic idle is almost since then.

Hey Guys After reseting the ECU I do not have that loss of power or white smoke anymore however I still have that erratic idle but it only last about 30 seconds after stoping and it only is whenever the engine is warm. Any ideas?

Coolant level did not drop. Oil level did not drop neighter. (last oil change 5000 miles ago) I done ECU reset today and will see how it goes and i will try to purchase that test for the coolant and I will update you guys how is it. thanks for your sugestions guys.

You mean Intake air temperature sensor turbocharger, signal ? where exactly can you make a foto?

Hi well i often use motorway and i had a trip last night for about 40 minutes on 3rd gear at 3300rpm but i still had that erratic idle today in the morning just after the car got warm, and ***** loads of white smoke but only for like a 2 minutes. and the car was already pluged in to the computer but everything is fine except 1 thing which is weird -40 degree on Intake air temperature sensor turbocharger, signal and that was checked on warm engine with +10 degree outside i will try to post pic later

Hi I Have Lexus IS220d from 2008 (58 reg) and 114k on the clock. I searched forum for issues that i have been experiencing but i see simmilar issues but not the one that I've got. On June 2014 I had my full service done, and that was the time when my problems with the car started. 2 Days after my service I had revs weaveing when stood on lights. (Weaved from ~~900 to 600 rpm) and when I had green I pushed the gas and I experienced loss of power and revs would not go above 1800rpm (No light at that point). I turned the engine off and back on again and it was totaly fine. Mechanic that've done my service said my MAF is getting bad and i need to get a new one as it works in like 60-70% (he said) and i bought new one from Lexus dealer next day. Next few days whenever the engine was getting warm the issue was happening again and again and the loss of power was visible (however whenever on cold it was like a powerful killing machine) Than one day after a journey I parked on the drive and I had that rev weaving again and i got VSC light on and the car just shut down (the engine just died like it could not breath) Checked few things on the internet (search for the cause) I had a massive carbon build up on my EGR My dad (Mechanic) he removed EGR from the car and gave it a proper cleaning. I always use Shell's, BP and Esso fuel After that car run fine for about two weeks and than it started to be happening again. From now on whenever the engine was getting warm white smoke started to go from the exhaust. (only for a while and it stops) I experienced a loss of power on a motorway it felt like i hit breaks hard for a split of a second and the car would not go above 1800rpm's and it was slowing down and down. i turned the engine off and back on again and the car was just fine and drove perfectly back home. And whenever I had such a loss of power simple restart of the engine would help.... This time i had pc pluged in to see whats wrong. It showed a low fuel pressure on common rail. And faulty brake sensor (the one under the pedal) This time my dad took out the EGR and Inlet Manifold (EGR was still clean after the previouse clean and the Manifold had like a half of Diameter due to carbon build up) And after my dad was finished with them they were clean as new. And I gave my DPF for restoration but the guy who made the restoration said it was very clean inside in a first place (mostly due to my heavy foot) So I changed that Brake sensor. (because sometimes it is an interferience that give false faults for something else) I had pc connected to my car and we took it for a spin. On warm engine i reved it on 1st and 2nd gear to 5000 rpms (limit) and it was just fine no problems what so ever. Than I called a guy from Terraclean to clean my engine from the carbon build up so there was nothing more holding it back. And the car was fine for 2 weeks and again i have those issues with weavy revs and engine is like choking (however i do not have that loss of power where it did not got above 1800rpm). Summary New MAF - from Lexus Dealer New Brake sensor - from Lexus Dealer Cleaned EGR Cleaned Inlet Manifold Cleaned Combustion chambers - TerraClean Cleaned Injectors - TerraClean Cleaned (Regenerated) DPF - which was clean in a first place Engine Oil is not consumed by engine (checked on daily basis) for a past 5 months Not to mention On town I have 25mpg and on a motorway about 36 with cruise control at 70mph at 2000 revs. Luckily I do not have that loss of power where turbo was like not working and car did not go above 1800rpm. Therefore I have no clue what cause that Revs weaving and suffication of the engine and lot of white smoke when engine gets warm. Please someone to help me.
