Lr3 06 4.4l v8 idle issue -throttle body?
Ok have an 06 LR3 v8, idle has been dropping for a while now. Gotten slightly worse over time, now occasionally it drops down from 1K to 100 and will die occasionally, when sitting in park in driveway.
Took to a independent shop, they are telling me the throttlebody is bad and needs to be replaced (electronic) no way to clean, only way to fix it is to replace it. he said he would get back to me with a price.
Is this normal? it has 53K miles on it. What do you think is the issue?
Plus inner tie rods are bad (new this was a problem, last time changed out the lower control arms, kept doing the vibration thing. this isnt the issue.
Thanks Nick

Nick,
I have a 05 LR3 HSE with over 225K miles. I do not remember at what mileage point this happened but I experience a similiar fault. My idle was fluctuating and experienced cut offs as well. I took it to the LR dealership where I've taken it for all service and repair work. After having my LR3 in the shop over a week they determined it was the throttle body. They replaced the throttle body and it corrected the fault. I hope this helps.

Take a 6mm socket, remove the cover over the engine with it, then use a flat bladed screwdriver and pull out the intake tube and then use some carbon cleaner on the throttle body and use a finger to clean it out. Reinstall the tube and the cover and start it up it and let it run awhile. then restart clear any codes that might occur from the excess carbon cleaner going gown the intake and you will be fine.
if it still dies then put a tb in it.

Thanks for the response. Cleaned the throttle body and the maf and everything is good. No more problems, just saved myself $300 plus dollars. Tie rods replaced, now she drives a whole lot better

Where the crap are they getting a TB out high fuel trims. Just clean the throttle body with carbon clean and perform a Fuel injection service but only if the vacuum test comes up clean. You can do that yourself. Just take off the hose from the aircleaner box and put a really big can that fits the hole exactly and tighten the clamp so its tight seal. Then start the vehicle and wait for the engine to stall, if you hear the squeeling sound then there is a vacuum leak and the vehicle is trying to suck air thru it. If it stalls without that noise then just do the bg fuel injection service and you will be fine.

found out the throttle body was just dirty, take it off and clean it and clean the air intake as well, solved my idle problems. Made the shop that told me it couldnt be cleaned do it. They said it was really dirty, no worries been a few months since and been driving like a champ since.
Where have you found a throttle body for $300.00? Mine needs to be replaced and the dealer quoted $575 for the throttle body with gasket, not including labor.
