I have a 2014 chevy impala with the 2.5 with the same po411 code and recently now if i cold start the car it will idle for maybe a couple minutes and stall but start right back up again , If i try to drive it , it will chug and act like its gonna stall i have to pull over shit it off and start again and sometimes it will go good again , Is all this related to the po411? And how far are you from maine? Please come fix my car
@@SmarOneNine I wish I could help, unfortunately I’m not close. Sounds like there is more going on, I never had stalling symptoms. Are there any other powertrain fault codes being shown?
i’m having stalling issues, and rough idle; usually after long highway speeds then stopping or slowly going uphill. Only code i have is p0411. Replaced o2 sensor, didnt do a thing. Going to try this before replacing secondary air pump
@@JohnSmith-nf8bi Sounds good, this takes more time but often this is the root cause of the issue and the secondary air pump is fine, in my experience researching this.
@@shibbyslayr1 it sounds like that is the case, the car in this video was diagnosed at the dealer as needing the ports cleaned, new valve and pump. I could hear the pump run on cold starts so I suspected it was okay. I knew that his car had been driven sporadically and not up to temperature over the past couple years, so I jumped straight to the ports and cleaning them solved my check engine light.
3/16" Drill bit fits perfect
My 2013 2.5 malibu doesn't have that air pump. I live in California, too. Maybe there were issues on some of those blocks and this was the answer 🤔
@@LaraHobbies they may have changed the secondary air injection system from your 2013 Malibu to this 2014 Impala

I can't find the expansion plugs. Anyone got a connection?
@@nb2481 they should be Dorman 555012
Do you know the part number for the freeze plugs?
Or the size of them?
They are Dorman 555012 :)
Ty appreciate it
I replaced secondary air injection solenoid valve and the check engine light came back on so I’m thinking I have to clean out the manifold ports too.

Nice video, i did this and the code still came back , how about you ?
The code did not come back for me. Check your secondary air pump and secondary air valve, those may cause the code as well.
@northeastbavarian4249 I cleared the ports, put new freeze plugs, and added a new secondary air valve still have engine code on
👍
Yessirrrrr awesome video man
Replace the valve , the pump , and do the cleaning , if there’s still a code clean it again
I actually just performed the cleaning and cleaned the valve. I did not replace the valve or pump. 5k trouble free miles so far.
Thank you
