Lunging during acceleration

[Pete165]

Check this small tube here to see if it's disconnected. Mine was for months after a plug change and was battling a surging issue. Sure enough, mine was disconnected.

Engine stuttering, slipping under WOT, no boost.

2014 Sport. Here's the problem. Under wide open throttle, Flooring the accelerator like when you pass another vehicle...or at least lets say 80% throttle or more. - Transmission drops a couple gears and the vehicle takes off, RMP's around 4k - All of a sudden the engine starts...

That was going to be my suggestion. Same thing happened to me - hose was off and caused exactly what you're describing.. Check all of those hoses, and could even be the solenoid itself

Since that solenoid is cheap and easy to get to, it probably wouldn't hurt to replace it anyways if you're getting up there in mileage, preventative maintenance.

Hello all,

I too am experiencing a WOT surging. I don't notice it any other time than WOT. At the suggestion of this thread, I checked all hose connections and it appeared okay. No codes, good power, just the slight surging at WOT.

Suggestions?

Another thread on "turbo lag" suggests running 93 octane. Maybe try that and post your results. I am considering, but not much WOT driving on my part these days

It might help but I don't believe the grade of gasoline is the issue as they all are able to run on 87.

Have you checked the throttle body? It is a problem with the 2016 model.
