Hello again, so there is a slow progress . I had the car smoke tested for leaks. One vacum hose had a little crack and there were 3 minor leaks that were fixed. One of them was on the LPG kit. so the car will go for inspection of the LPG. Hope the results will get better after that.

Hello again, so I replaced MAF sensor, and after few days of driving no change in engine performance...§ Next thing will be inspecting CATs.. and O2 sensors.. lets see if there will be any improvement.

Hi I have tried multiple versions of TS and also tried to connect other toyota models and it always chose automatically the model. I have European version which may be different. I can only chose if it is Landcruiser or Lexus and then some production periods (3 or 4 options). Engine is loaded...

Hi oakback, thank you , I can check injectors the way you described, but assuming the performance issue is there also when running on LPG, ijectors should be OK as those inject gasoline. Just my thoughts..

HI 2001LC., the engine is 2UZ FE, see picture there are also the LPG setup.. and regarding the values.. I did a quick measureing of O2 as the engine was hot (87C) and see the graph below.. I am dont understand why there are values almost at 0 V when Idling after engine was revving for a...

Hi I prefer to buy parts by Toyota dealer when I am 100% that the parts wrong. They are not the cheapest :( I have a endoscope camera so inspecting CATS mihht be easy . Just.. time is the issue :) I ahve checked my TS for misfires and this feature is not there.

Hi 2001LC, thank you for your detailed email. I will for sure need to check for vaccum leaks. After cleaning MAF the performance got slightly better, but still there are minor shakes. I will try to find someone nearby and try to make swap if that helps. I have replaced recently valce...

Hi I measured resistance on MAF and compared to factory specs and those were not quite aligned. Also live data claims that it measures approx 3.9. Anyway I will try to disconect it and see how the ebgine performs. I will send update soon

I tried disconnecting coils but after each the engine performed worse so it is hard to tell which one could be soon gone. I also dont get any DTC s or Check engine light.

Hi, thank you for your advice. I will try and hope for the best. Will see

Hi to all , I am experiencing an issue with engine performance resulting in poor emissions - high CO2. I do not get an DTCs nor MIL is illuminated. I checked data via Techstream and also made graphs of O2 sensors as I was suspecting them to be faulty. I have attached graphs that I measured...

Hi to all, this topic is still ongoing. but now it seems to be a bit worse. I did not use the car so much and was more standing parked then driving. Now I plan to use it more and also emission test is in a few months so I should dig deeper into this. I have tried to graph the performance but...

yes , I know it took me a long time to find out but finaly I did it. One more thing to mention I did not replace them for original ones but polyurethane one.. (color blue - do know know if it is important)

Hi Finaly got rid of vibrations.. I had to replace all bushings on rear arms. Tested today by 160 kmh and no vibration also by decelerations.. I am now enjoying the real comfort on highways :)

Hi, I have noticed that when RPM bounces and I switch it from LPG to petrol it is not that significant.. I will need to have the LPG system checked probably. Or could it be that the spark plugs are an issue? Has anyone similar experience? Thnx
