Flxr_88 Posted May 23 Author Share Posted May 23 (edited) Thanks. I have found it and that’s what I’m following. I searched it up, and It looks like I have 2purge valves. It seems like they just added another plug to the mix and slapped it on. Should I tape off the end of the old plug and use the new one or would the ecu not recognize this new sensor? Or is this another sensor altogether? Edited May 23 by Flxr_88 Link to comment Share on other sites More sharing options...
KZJonny Posted May 23 Share Posted May 23 Hard to tell exactly, but I think that is the purge control solenoid (black wire connector) and your boost control solenoid (blue connector). Purge solenoid shoudl have 2 posts on it. On from the fuel vent line, and the other to the IM. Yours looks like one is broken off. Link to comment Share on other sites More sharing options...
Flxr_88 Posted May 23 Author Share Posted May 23 (edited) Yes one broke off. I’ll get a new one on order. It seems like the piece broke off and they despised to just bypass it. Other than that everything was pretty close to the diagram. Edited May 23 by Flxr_88 Link to comment Share on other sites More sharing options...

And I don't know exaclty what would happen when you cut the reference line going to the turbo. I would think the wastegate would mainly stay shut, since that is the default position. So... you could probably build a lot of boost and not know it, especially if the vacuum sensor was not attached. Might explain the crazy noises and very loud bypass valve? When I said 'damage stuff' earlier, it was less about damaging the turbo... as long as it has sufficient oil I doubt you'd be able to spin it fast enough, it's all that extra air pressure having to go somewhere. That's the kind of thing that breaks ringlands, especially if it's not being accounted for with more fuel and the engine is knocking. But as you said, it was a short drive and you pulled it right back in, so better than having gone for a spin like that. Hopefully with all this stuff fixed, and every hose connected to where it is supposed to be, you get back to normal. Link to comment Share on other sites More sharing options...
Flxr_88 Posted May 24 Author Share Posted May 24 Took it for a test drive yesterday, and drove it around today. Everything seems fine, and better than before. Idles better, the Cobb tuner is reading boost, and no noises that sound out of the ordinary. Thanks for all the help and this is a big peace of mind knowing that this fix will be less likely a cause for something else in the future. 1 Link to comment Share on other sites More sharing options...
