No vacuum at FPR, no leaks, confused.

[theother1wstolen]

i have no vacuum on at my FPR and i cant find a leak anywhere, i used a propane torch and checked spot, nothing, cant hear a leak either. yet i have no vacuum at the FPR at all i pull the vacuum line off of it and can hold my finger on it with zero suction at all. so can something be clogged and causing me to not have vacuum where i should? IACV perhaps? any suggestions would be greatly appreciated. also all of my vacuum lines are new silicone hoses.

I have never had much luck with the spray water/propane/wd40 to find a leak.Sometimes you get lucky and the hole is on top of the hose where you have access to it. But a lot of times the whole is in a place that you have zero access to.

Take it to a shop that has a good smoke machine ( they cost over $2000+).They have machines that can find a leak as small as .020 thousandths of an inch.

A shop can easily find the leak for you (if there really is one) with their smoke machine.

FOLLOW THE HOSE TO THE MANIFOLD AND SEE IF YOU HAVE VACUUM FROM THE MANIFOLD AT IDLE.
