Buick lesabre surging, part 2

[@jrfmechanical3058]

Thank. Positive crankcase ventilation (autospell) Yep. Somehow it was missing, and that what made it act weird. Getting rich fuel from somewhere which was the pcv.

[@jeffreyhoffmann2176]

4yr old video helped me out. Thanks

[@jrfmechanical3058]

Lol

[@robertsmith2956]

I was wondering where that bugger was hiding. Under the MAP sensor, how could I be so stupid. LOL

[@ItsaRomethingeveryday]

This same thing caused out car to stall and not restart, got one from pick a part for ten dollars and now car is happy, Liked your vid Btw, it's a Pcv valve, not pvc

[@brucebehnke3227]

MAF SENSER & DISCONNECT BATT & RESET COMP. BET IT WORKS

[@practicalapplications8899]

Why would u take it back out? If you install a part it stays.

[@jrfmechanical3058]

To show what happens when it doesn't work, like stuck open or missing.

[@Goodluckchuck0711]

were you surging idle? mine is surging in park but doesnt go to high maybe 1400 but then goes down like it wants to die. drops to 3-5 rpm for a bit then jumps to bout 8 to settle

[@jrfmechanical3058]

No. Just reving it, then it got that extra fuel fumes into the intake. So that was the cause of it. Just getting more rich and couldn't idle.

[@bigspeaker781]

I think this is my problem I’ve been replacing everything and it still does both.

It's PCV brother. PVC is a type of plastic tubing usually used for irrigation.

[@jrfmechanical3058]

@@MrJwtaylor40 I said it too fast. Positive Crankcase Ventilation

[@ancient_shadow7157]

That wiggle test you showed. I did that on mine and some liquid came out but my car is running a lean code. Either way, what do I replace or do to stop that piece from having to much

[@jrfmechanical3058]

PCV . Postive cranckcase ventilation. Replace that.

[@jerrypeal653]

You got your point across so I don’t know what these criticisms are about. Grow up people !

[@jeremyderr3310]

Mine is running uo to 60 and bogging down. Dies when going 30 or lower.

[@jrfmechanical3058]

Might be the same ]problem

[@wadedavis2334]

I am currently seeing all the same things with my lesabre and it almost dies after I start it any tips??

[@wadedavis2334]

It also surges after I’ve been driving it down the road when im waiting at stop lights

[@jrfmechanical3058]

Replace the pcv valve

[@brucebehnke3227]

MAF SENSER 😉 ! I KNOW I WENT THROUGH IT ALL

[@brucebehnke3227]

​@wadedavis23 maf senser been there !😂

[@delcorick9967]

I don't think you had pcv valve in their to begin with, it didn't come out with the map sensor holder nor was it in the plenum from what I saw, regardless I hope u figure it out

[@jrfmechanical3058]

I did.

[@Bruce_R]

Hey, did changing the PCV valve work for you? Wasn’t able to find the part 3 video. I’m having the same sort of issue on my 2002 Lesabre. Getting hesitations around 2500 RPM. Check engine light went on for the O2 sensor bank 1 sensor 1. Had my fuel pump, fuel filter, air filters, catalytic converter all replaced because the car has been sitting for 2 years

[@jrfmechanical3058]

Yeah. Mine was stuck wide open. So it was running too rich from the blow by. Replaced it and it's better now.

[@Bruce_R]

@@jrfmechanical3058 Gotcha. Did you get a check engine light on yours? Mines giving me the PO131 code. Thanks for video, this has been super helpful!

[@jrfmechanical3058]

@@Bruce_R no check engine light. I was replacing ther intake gasket. But running rich.

[@adventureoflinkmk2]

​@@jrfmechanical3058hey does lack of o ring also cause the surging

[@mr.fredricklawngtawnghedav5094]

Try cleaning the throttle plate and throat. A little grime around the throat can restrict enough air to give inacurate readings to the computer.

[@garyhall8308]

Watch someone that knows what they are doing because there is a o rig that goes around the PCV valve it doesn't just drop in.

[@jrfmechanical3058]

I believe it was already on there

[@garyhall8308]

I'll drop the replay flag on that one.@@jrfmechanical3058

[@reggiehowze1891]

You forgot to put the o-ring back on new part

[@jrfmechanical3058]

Opps

[@reggiehowze1891]

Lol. I learned from experience. Thanks

[@adventureoflinkmk2]

​@reggiehowze1891 yeah was gonna say I just redid my intake manifold and both times I changed it I forgot the o ring for the pcv.. ope

[@jrfmechanical3058]

@@adventureoflinkmk2 dang. Alright, get that on there.

[@adventureoflinkmk2]

@@jrfmechanical3058 would if I could but JUST when I got everything buttoned together and for the first fire (which surged idle.. again.. and somehow the MAP sensor mounting came back loose?) I had to take my fiancee to the hospital.. her arm and shoulder were bothering her all weekend

[@timayscott8450]

Oh i feel sick

[@7denots10]

Jesus Christ if you shook the camera around a little more I might be able to see 🤦‍♂️

[@JalopyTechnology]

PCV.....

[@jrfmechanical3058]

Yep. PCV

[@jimellerman5686]

pCv valve NOT pVc!!

[@jrfmechanical3058]

I know, i mis said it. Postive crankcase ventilation.

[@johnwagner4559]

Looks like u forgot the oring on the pcv valve. Need better camera work, genius.
