Basically, the current situation is that the engine will start, and if completely cold, for the most part seems ok. The trouble is if I stop the engine and then go to try to restart it, the thing dies almost immediately and is a bear to get moving. If I get it moving without letting off the gas (highway or interstate), it generally seems fine, and if I stop and let it idle, it seems fine, but then as soon as I kill the engine and then try to restart it, I have a miserable time keeping it running long enough to get moving.
Any and all advice greatly appreciated.... before I take it back to the $hop...which is what SWMBO wants me to do.... I'd much rather fix this myself if I can.
Here's the history....
June 2018 @ 237,855 miles, I submitted this thread:
CEL P0234 and P2097
At that point, the resolution was that I ultimately handed it off to my local indie shop and they replaced some vacuum line and the Turbo Control Valve/Booster Control Solenoid, which resolved all issues.
May of 2020 @ 263,000 miles, I submitted this thread:
V70 2.4T (P2) ECM-262A (P2097) - upper O2 sensor?
In that post, I got the suggestion to replace the vacuum lines around the Turbo Control Valve/Boost Control Solenoid and connected back to the turbo, which I did. It was also suggested that I replace the Turbo Control Valve/Boost Control Solenoid, which I did NOT do, because it hadn't even been 30k miles since it had previously been replaced.
At the same time, I decided to go ahead and replace the larger diameter evap lines. I purchased 3/8" fuel line from the local auto parts store (it was the closest match they had)….but apparently the size wasn’t the proper fit (it was slightly too small and I did have a little bit of trouble with some of the connections, but was ultimately able to make it work).
Anyway, after replacing the vacuum and evap lines, ALL of my problems seemed to go away. (Note, I did not replace the lines going back to the evap canister/fuel pump - only what I could reasonably get to on the top side of the engine compartment).
That code cleared, stayed cleared, and I was able to pass emissions inspection.
Awesome!
Fast forward to a few months later, and I started having some of the same issues - not staying started, not wanting to start up well after a short trip, hesitations, etc…. It started slowly at first, but now it’s gotten to the point that if I drive a short trip of just a few miles, and then hop back in the car to drive back a few minutes later, I almost can’t get the car to stay running long enough to get it into gear. Lord help me if I pull into a space and then have to back out…. It’s almost impossible, unless the car cools down completely, or I sit there and rev it up to 4k for a while to get the engine running. Once I get moving and have the engine under load and going down the road it generally seems fine.
And its throwing the SAME DANG CODE: P2097 (using the Torque app on my android tablet, because it is fast and convenient).
Yes, I have VIDA, but I didn't feel like pulling out the laptop...and I'm not terribly familiar with how to use all the bells and whistles. The last time I used it was for this issue last year.
August 7 (@273,087 miles), I got a misfire in cylinder 5 and replaced that coil. I noted a LOT of oil collected in the spark plug well, which the Indie shop has SAID is not that unusual, but I'm second-guessing that... Cleared the codes and thought I was ok, because it seemed to start behaving again....
Speaking of which - I last replaced the plugs Sept 2016 @ 212,042 with NGK Iridium IX 6418 plugs - 61k miles...so probably about time?
I've done a visual inspection...but not much else until today. I had a writeup all ready to go, but didn't get it posted this morning, and then had to go somewhere, and had issues again, so I very quickly (and in a quite irritated manner) replaced the Turbo Control Valve/Booster Control Solenoid with a brand new one from FCP Euro that I had bought a while back just in case, and the problems seemed to go away immediately....but that wasn't it, because the very next time I stopped and went to restart, I had the same issues. a few hours later, and I had to restart at least 4-5 times before I could get going. Drove on the interstate for 10 minutes, got home, stopped and let it idle, and it idled just fine for 10ish minutes with no issues.
Side note - on my visual inspection, the larger evap hose has split in several places. I'm not sure if that's all the way through, or mainly cosmetic, but I probably should replace that with the correct size tubing - who can tell me what that is and where to get it? If you're not sure what hose I'm talking about, see the pictures. And as a side question - what is the white fitting in that line? a 1 way valve?
Thanks!
