So my car has started driving wierd lately.... I noticed the nice boost leak the other day( ive been driving without spooling the past 2 days) which will be fixed hopefully tomarrow, and then today it started ideling all irratic, a quick climpse to the boost /vac gauge and the vac was jumping from 25 to say 15 or so.....


Well I recently installed a megan exhaust manifold, and turbo outlet and used their gaskets instead of the metal stock ones? What are you guys using when swapping the stock parts out? Is the metal ones better?

Thanks in advanced.

 

Exhaust gaskets wont cause a vacuum leak. Maybe you forgot to hook up your vacuum/boost line on the nipple on the turbo outlet

 

Yeah exhaust leak won't cause a vaccum leak. Check for a disconnected or cracked/broken vaccum line. Or, your boost leak it so bad that it's causing a very noticable vaccum leak.

 

well it ended up being the EGR control valve, Two of the three hoses broke off with the nipple still in them.... I ordered the new part for mits, and it should be here on monday.... Anyone have any idea on how to replace that thing..? thanks guys
