I shall call you my brother and will now thank my brother for this simple and effective video! Been chasing this issue for the last week on a customers car seeing no external vacuum leaks after i fixed all them and still had the issue. Sure enough i did what you said and boom. Car immediately smoothed out and danced for joy cuz now you’ve learned me something valuable!

[@robertwhitworth7346]

I know this is late but just happened on this video, wishing you well in your recovery, I love watching your videos, you both work so well together!

[@autobuff6598]

prayers for a speedy recovery, we missed your video updates.God bless

[@shanescalise7643]

You are the first person to explain this. Everyone else just wants to talk about the issues it causes, not what a bad one looks like or what its actually called. Thank you sir.

[@be9concepts]

I don’t think this is our issue but I learned a lot and will check this after replacing coil packs and cleaning tb and maf. 01 Passat 1.8t

[@stancarney3753]

I spent a fortune trying to fix bank1to lean But it's fix now thanks to you I wish you well

[@jamiejonesthecarman]

awesome, yes vw dont do good with airflow issues lol

[@alexandrudantoma4365]

Guys you are great the way you talk i can tell you are great people and i wish you from my heart all the best and good health ! take care !

[@gregorythoman8281]

They are called Oeticker clamps. Sometimes they are called ear clamps or double ear clamps depending on style. There is a special cutter that makes removal very easy. I got mine on Amazon for $60. You can get cheaper ones but I got a double action one which makes it easier to use in tight spaces. Worth the money guys.

[@codeyhanna767]

Thanks for the vids. I watch all your videos and enjoy your channel. Good luck on a healthy recovery :D

[@therealkendravlog7656]

Thank you guys alot thats save me money when i have the same code on my car and what i did temporary is plug the hose so no air is going in on the engine

[@lotdominguezcastellon6028]

Hi, on a 2.0 Jetta 1999 where is that valve? I have the same p0171

[@johne3983]

just bought a 2000 VW passat and it's shifting hard.. went to check the tranny plug and it's huge.. 17 MM to be exact! so I'm on the hunt for a big enough Allen wrench

[@stephendelgado2565]

it's so hard to reach but i will try it. coz the auto repair shop told me that i don't have this kind of parts. i guess they're lazy to repair

[@tomjames9498]

Thanks mate! You've just helped me find the problem on my 1.8t seat leon cupra, subbed!

[@tomjames9498]

I'm getting the p0171 code which this has fixed the problem, but I also have a serious cold starting issue, would this fix that also?

[@rjreyes8529]

Hey hope your well with your health, I drive a 2004 Jetta GLI 1.8t and it has bank 1 system too lean and it idles fine but has a little drop in it at times and the main part is when I get into boost it tends to studder and it seems like the injectors I would think but what would you think it is?

[@robman38]

Thank you for sharing! Wishing you and health and happiness for many years to come. PEACE-OUT! - ROB VANCOUVER, BC.

[@sinissster9657]

I have lean code saying to replace maf did that as well as some pcv hoses and pcv. I’ve also got a completely cracked exhaust after the downpipe right before both 02 sensors. My symptoms are rough idle car shuts off at stops. Wonder if the exhaust could cause this?

[@erickmendoza1206]

Great Video. Hope Health continues to improve!

[@barrygilmer2683]

you always have good info

[@jamiejonesthecarman]

+Barry Gilmer this tip will save a lot of money lol

[@onebalkan2744]

great video man:) thx a million.

[@jbcappella]

Can that valve can cause my idle to drop down around 5-800 and then jump to 1200? And occasionally stall?

[@papichulo6258]

Much love from Houston Tx. G.B (u)

[@coltonfrancisco7090]

Could that valve being stuck open cause my turbo not to spool as much? I have a feeling this is what it's been but haven't bought the part

[@jamiejonesthecarman]

Absolutely I've seen that thing either stick open or closed and screw up more Volkswagens you can shake a stick at like it is a serious problem but thank you so much for watching I'm always here if you need me and we've got new content coming out of every week so just join the channel and join our community thank you

[@onebalkan2744]

thx a million man:)

[@chrismcfarland996]

so I have a misfire in all 4 cylinders would that be the problem or no

[@gregorythoman8281]

Yes

[@blacktielimousines5136]

I have a 2006 VW Passat 2.0t. I had a misfire Cylinder 1. I replaced all 4 spark plugs and all 4 ignition coils. It idles fine, but when you give it gas it runs like it is missing bad. Also, had a code for crankshaft "SLOW RESPONSE". Can you help me?

[@MrJerryHsu]

Randy Wiggins Simple things first. Replace your fuel filter located under passenger side. Check for vacuum leaks. And check all fuses. If you have cold start rough idle and long crank with low fuel pressure, then possibly high pressure fuel pump failure maybe from worn camshaft intake exhaust. Check your cam follower on the pump. Or faulty crank shaft sensor, located left top behind engine on passenger side. If no power in 3k-5k I would check for dirty throttle body and then think about cleaning intake valves if issue persists.

[@fotlitbowfotlitbow5514]

Is this a likely case with jetta 2.0

[@lisathomas2639]

Please advise the link to your channel. Thanks

[@kyletrooper6558]

Is this called a PCV bypass valve? I have an 03 passat 1.8l turbo. would that be the one I need?

[@jamiejonesthecarman]

yes sir but you can replace the hoses for next to nothing, i would do it all and fix it for good

[@joshuagallup4024]

[@logandiamond5606]

[@sambannister4598]

what is the name egr???????valve

[@briancarroll6430]

I have a 2003 vw passat 1.8l turbo and it idiling. Rough and I'm trying to figure out what's going on with it

[@briancarroll6430]

Can you help me I put new spark plugs and ignition coils in it still idling rough

[@jamiejonesthecarman]

Hey Brian, go to my VW Playlist. I just put it up today and look for the video about a lean code. It causes the car to run really rough and it its just an air flow problem. I'm not at home at the moment to look up the specific name of the video for you, but I will try to check really quick from my phone and see if I can locate the title. This code causes the car to idle very rough and causes multiple misfires too.

[@joseb1700]

Hey I got a p0171 code checked for leaks with starter fluid n hissing, but I got nothing . Car runs good only noticed a lil loss of mid range power. Like between 3-4 gear . Almost unnoticeable. But the strange thing is my transfer pump was humming real loud but the noise stoped n all of a sudden I get the chk engine light p0171 could that cause it? I’d think I’d get a low pressure code? I’m disabled n spending 500-1000 $ on a repair is not in my limited budget. 1 more thing is I changed my primary pump not long ago, could I have not tightened the big ring on the fuel pump n gettin air into the tank improperly sealed. I changed it like 2/3 months ago maybe around the time I was feeling the loss of midrange power? Sorry for the documentary. Please help I need it👍🏻 also get better I know how it feels to be down or I’ll . Also I have a 09 Tiguan s 2.0t

[@jamiejonesthecarman]

+Jose B fixed problem yet

[@marktrainer8176]

If this is the problem for the P0171 code, is it still good to drive the car a Lil bit until I have time to fix it?

[@gregorythoman8281]

Poor gas mileage and the catalytic converter can get screwed up. The engine is sensing a lean condition that is not real so it adds more fuel. The excess fuel is not burned so it gets dumped into the exhaust. The converter trys to burn the excess hydrocarbons and it will get very hot and can be damaged. If you have to drive make it very short trips.
