i put my blitz bov on and now my car has a bad idle and shuts off when i drive and stop at a red light. i adjusted the screw where it controls the spring but the is another bolt near under the vacuum line. is that the other i need to adjust to get my idle right?

 

Sounds really like you have a vacuum leak - not necessarily from the BOV itself, but from what all else you un-did to install the BOV.

Did you get the kit from Blitz that replaces the turbo outlet pipe? If so, check the intercooler couplers and make sure they're on good and tight. Also check the air line going to the BAC.

This is gonna sound bad, but did you plug up the gaping hole in the intake? Where the stock BOV would vent into the intake?

 

yeah, makew sure its not another line before going and adjusting your BOV. it seems that you might have another leak somewhere else.

 

yes i did plug up the hole. i also looked for any other leaks didnt see any. just bought a tps the other day used, possibly that? what my idle does is it idles at about 800 and it will putt and sputter down to like 700 and then the engine shakes. almost idles good but still has the shakes.

 

I have the same BOV....and did not have any issues with it after the install....its been untoched out of the box and has been performin great.....sounds like u have a vac leak some where or (not to say anything against u) have the vac lines connected incorrectly.....

 

will the blitz BOV work on a stock turbod, stock intercooled TII ? Sorry to go off topic...

 

i put my factory bov ( by-pass ) on today and now the idle is fine. could the blitz bov be bad?

 

Do you have a series IV? If so a Atmosphere vented blow off valve can cause idle problems because of the flapper style AFM. The ecu gets confused because it is anticipating the air coming from the bypass valve to go back into the system. I heard you have to really tighten up that screw to get it to work on a series IV.

 

thats what ive got.....i'll post a pic later

 

Heres the pic....not exactly the best pic
