Ktmking250 Posted April 19, 2012 Share Posted April 19, 2012 Revised timing, make sure to check your to check your vacuum lines. You have a leak at your MAP sensor. That is the message I received with my last tune revision. I'm wondering if anyone can shed some light on what I am looking for? I went thru and didn't see any lines disconnected from when I installed everything. If you have any suggestions I'm open too. And where would the MAP sensor be at?

Moderators BarManBean Posted April 20, 2012 Moderators Share Posted April 20, 2012 check the T-connector under you intercooler, intercooler TB hose, and BPV sense hose. I ziptied / corbin clamped all of those during my stage 2 install--you should've done the same. Not a big deal if you didnt, just have to pop the intercooler off and go at it.

Ktmking250 Posted April 20, 2012 Author Share Posted April 20, 2012 well i added some pics of the connectors i think that are in question and they have zip ties on them let me know if im missing something or looking in the wrong place thanks again barbeanman 1 Link to comment Share on other sites More sharing options...
Moderators BarManBean Posted April 20, 2012 Moderators Share Posted April 20, 2012 looks good. cant see bpv sense hose, but that would be the most obvious leak ever (to the right of the intercooler as you look from the front of the car. One of the "t hoses" goes down and it's also suggested that you clamp it, but I'm not sure which one, sorry. I have an image, but baby is crying, brb.

MrHellrais3R Posted April 20, 2012 Share Posted April 20, 2012 Your map sensor is connected on the same bracket that your boost control solenoid is bolted to. It's above your turbo inlet in front of your intake manifold. It has a vacuum fitting that points down and connects to the nipple that comes off of the front lower middle of your intake manifold. Go search for vacation pics If you have more questions about where things are. Or look at the vacuum layout diagram under your hood. Link to comment Share on other sites More sharing options...
Moderators BarManBean Posted April 20, 2012 Moderators Share Posted April 20, 2012 The other one I was referring to is the one that goes to the manifold. See image.

Ktmking250 Posted April 20, 2012 Author Share Posted April 20, 2012 ok i think this is the issue? how come this would come off, does this have to do with the boost blowing it off? And this is the map sensor leak the tuner was talking about? 1 Link to comment Share on other sites More sharing options...
MrHellrais3R Posted April 20, 2012 Share Posted April 20, 2012 Yes. Map sensor measures manifold pressure. It probably came off from boost. Just zip tie it. Link to comment Share on other sites More sharing options...
Max Capacity Posted April 20, 2012 Share Posted April 20, 2012 Look around further, there are more vacuum hoses that need to be zip-tied. Some are behind, under the intake manifold. Then look more, any vacuum hose should be zip-tied. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

MrHellrais3R Posted April 20, 2012 Share Posted April 20, 2012 ^ yeah there are emission vacuum lines that under under the manifold. There is an air surge solenoid that is on the same bracket at the map and ebcs. Its lower and pushed back a little under the manifold. It has two nipples on it for emissions. One hose goes to the back of the manifold (that one is hard to see), and the other one goes to the nipple right at the front of the manifold that is that big circle in the front.

Ktmking250 Posted April 20, 2012 Author Share Posted April 20, 2012 In the picture: the line thats off, if you follow that back theirs a round thing with a foam outside. In the picture it's just above the blue connector, what is it sms if the foam is deterating should it be replaced? Link to comment Share on other sites More sharing options...
bmx045 Posted April 20, 2012 Share Posted April 20, 2012 lol @ this thread. zip tie that vac line, hoses that arent connected to anything are a problem with turbo subarus. and guess how i blew two pistons to death? a disconnected map sensor line that blew off(from what i can gather).

bmx045 Posted April 20, 2012 Share Posted April 20, 2012 the foam is a check valve, it may be fuzzy and ripped, that's fine. just make sure the ***** hose is conencted and let it be Link to comment Share on other sites More sharing options...

char kuey teow Posted April 20, 2012 Share Posted April 20, 2012 OP: how did the car drive with the vac line disconnected? Did you have noticeable drivability issues? I'm curious. I recently did an e-tune which was pretty exciting for a while but now it seems the car is lagging power at the low end. Thanks. Link to comment Share on other sites More sharing options...
Ktmking250 Posted April 20, 2012 Author Share Posted April 20, 2012 I haven't noticed anything real big. Maybe little rough idle or hesitation at idle but no major loss of power. Won't have know otherwise if the tuner didn't mention it Link to comment Share on other sites More sharing options...
Refuge Posted April 27, 2012 Share Posted April 27, 2012 (edited) The other one I was referring to is the one that goes to the manifold. See image. So, are you referring to this thing under the red circle? There is a hose that feeds towards the passenger side direction that is loose. Do you have to take the major top half of the engine off to reach it? Edited April 27, 2012 by Refuge Link to comment Share on other sites More sharing options...
Shello007 Posted November 1, 2012 Share Posted November 1, 2012 ^ Hope this is the cause of my problems. Running super lean, after installing aftermarket inlet hose. I did notice during re-installation of engine partss, that the tube was very lose. like almost unable to stay in place. BTW, whats the foam around that plastic thing for?

mtlsubynoob Posted March 26, 2020 Share Posted March 26, 2020 Hey guys, i need some help with my 2005 legacy non turbo. the engine shakes/misfires only when im at a complete stop, once I take off, the engine seems to settle. I feel like its a vacuum issue bcuz i had a jetta before and it had the exact same symptoms. my mechanic nephew already changed coil with wires and plugs, and a new battery ( not related lol) if anyone can give me any advice or know of common hoses that crack and lose vacuum, that would be greatly appreciated Link to comment Share on other sites More sharing options...
Max Capacity Posted March 26, 2020 Share Posted March 26, 2020 A smoke test of the vacuum system would be the next step. He can blow smoke into the system and see if there are any leaks in a hose. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

Wouldn't hurt to clean the maf sensor too Link to comment Share on other sites More sharing options...
