I have been doing some searching around and found a reference to a TBB tare, something to do with hoses i think. can anyone enlighten me as the what TBB means?

 

throttle body boot ... at the bottom of your y pipe

 

and TB can be timing belt sometimes watch out!

 

Thanks guys I just had the Timing belt changed so if it is that then there is a problem but I will either check or have checked the Throttle body boot.

Would that been torn throw the codes P1411 and P1423?

also what would be the consequences of it being torn?

 

runs like crap

 

boosts and then studders as charge air leaks out of tear, A large boost leak is something you only have to experience and wonder about once, everytime after the first you will know exactly what is happening
