Went to clean my throttle bodies today to see if I can sort my high idle problem out, started cleaning them with a toothbrush and the dam thing snapped, tried taking the throttle body off but diddnt know how to take it completely off so I looked up on the internet and found that I could access the toothbrush by removing the balance bar, anyway, I managed to get the toothbrush out, I tightened the throttle body back up and put the balance bar back on, my question is, will I need a new gasket for the throttle body and what is the best sealant to use to seal the balance bar back up as their is now an air leak? The idle is still a little high, just above 1000rpm, I think it must be something to do with the maf or tps.

if your lucky and the TB gasket has'nt ripped by sticking to either the plenum or TB itself then its possible to re-use although i would replace later to be on the safe side. as for the balance bar, there should be three rubber "O"-rings which can be brought from any decent hardwear store. gasket sealant can be used but these rings are a much better option.

Thanks mate, have you got a link on how to remove the TB to be able to fit the gasket as the gasket has split?

 

Thanks

they are fairly straight forward. its being held on by four allen bolts (that are FT), there is a vac line under the body that needs to be removed and two water pipes, both the water and vac might have enough give to be left on if not then they have to come off. obviously the intake pipe needs to be removed. once all four bolts have been taken out then a gentle tap with a raw hide mallet will free the TB then it should slide straight off the throttle linkage bar. nice and easy :D

Thanks for the advice, will sort it out next week, will it be ok to drive or should I wait till I get the air leak sorted?

it should be ok to drive, you will be surprised with the amount of zeds out there on the road with boost leaks. obviously dont go thrashing the crap out of her but get it sorted as soon as you can

just a quick question...... how far into the plenum did you clean to get access to the tooth brush via the balance bar?

Just cleaning as far as I could reach, got hold of some wire and managed to push it to the balance bar opening.
