You have to open the TB throttle plate to clean it. Moving it will not mess anything up, its impossible.

 

Thanks, I will clean TB and I have ordered new MAF sensor. Does anyone know how to check fuel pressure? I have never done it on 4.4 LR3 and from what I understand, gage has to be connected to both sides of the fuel rail.
If that does not fix it I will look in to O2 sensors like Dakota mentioned.

 

Thanks guys,
It was the MAF sensor and i have to share with you, my disappointment with the market today that will charge me and you guys 4X more just because we own a Land Rover and we have more money than someone that drives Fiat that is not truth at all. Ok, to make story shorter: Toyota uses the same MAF sensor as LR on 4.4l that i got for 5$ from wrecked Lexus.
Cheers

Hey Doug,
How long you have been working on LR's?

 

Since January 26, 2016
This one is my first :-)

 

Yes its a Denso sensor. It even says so in the literature. Alt sources have been covered many times on the forum. Glad you got it fixed.
