Bad BOV

[SHOdded]

Did you replace the front BOV as planned prior to the dealership getting involved?

No. I did check it but it doesn't look bad at all

You tried swapping them tho right?

I would buy a new BOV and replace the front.  Small investment for such a longstanding headache.

It looks like NO one has changed the BOV!  Z

No! The Front & Rear ports work on vacuum and don't need hose clamps  Z

So I disconnected the front connector and its not doing it no more. They do sound a lot louder.

I really appreciate it that bro. Let me recheck them again. I will let you know. I've noticed that it's not doing it all the time. Once I turn my car off and on It acts normal. I'm thinking something electrical is wrong

post a new datalog of the issue in a 4th gear pull .. i'd like to peek at it doing the issue for 10 or more seconds. 

fixing itself on a stop start suuuuuuuux,  that means a sensor is bad or sending a bad/incorrect signal,  or the ecu has a bad block that clears on reboot.  does it fix itself EVERYTIME you do a 35 second cycle of having the car off... and how long in the start up does it run normal before the issue occurs?

and completely random idea.. does it do it COLD.  IE water temp is 110f or less, and the car is still in ''warmup mode''.  does it happen there at all?

Sorry I haven't replied. Been working a lot. So I noticed that it only does it some times I'm thinking it's the ECU.
