The previous time my car was in a limp mode, because of one ripped pipe. I replaced it, now i`m having my stock power.

Could you someone explain me what is TBB (throtle body boost)??

Second thing! Could it be that because one of the exhaust temperature sensor my car doesn`t have it`s chip power.??it`s stock!!!


Thanks in advance!

that`s exactly what i just changed ..there was areal big hole!!!

but it`s not good enough!~

 

Do a pressure test to locate your boost leak..if that's what it is. Search for pressure test, homemade pressure tester, home depot pressure tester...etc.

 

tbb = throttle body boot

 

i'd deffinatly pressure test your intake system, the s4's have multiple hoses that like to give out, f hose is another common failure

 

im sorry....but is a "f" hose
