after removed and reinstalled the whole intake mainfold
my car refused to idle

it will rev up to 3-4000rmp then die
i have to hold on the gas to keep the engine run
anyone get an idea?
vaccum leak?
i am sure i had everything back on the right spot

 

forget to mention
i have a gsl-se

 

AFM plugged in? What about the hose that goes from the top of the inlet to the RE-EGI box? How about the BAC valve hose (Is it connected?). Maybe where the section of the inlet duct join together (near the AFM).

 

Yes, it does sound a leak from somewhere around the AFM or the intake. That is exactly how they act.

 

checked for leaks today
seems like it's not the problem
will try that again tomorrow

 

Air fuel ratio adjustment, but that doesn't sound like the problem......

 

it's the Air control valve that gone bad
