Why Does My $600 Volvo 850 Wagon Buck Like A Bronco??

[@raycasson1774]

The volvo ain't what its quacked up to be,says the duck...😂

[@gs4u2c]

I'm a Saab guy, so take this with a grain of salt. 1. Try to run it with the MAF unplugged. 2. Check the throttle body, perhaps loose/leaking butterfly. 3. Might be coolant temp sensor whacking out the computer... My $.02 Love the channel Mike.

[@chrisparenti2461]

I wanted to thank you Mike for helping to replace the fuel pump in the 98 explorer that I now own. I should have it sometime next week 👍🏻

[@asifkazani523]

That Explorer is awesome 👌 Good luck and enjoy

[@dizrick]

Not a wasted day on our end Mike. Love watching your videos.

[@rjkdev]

Love seeing your dog and duck in all your videos! 🙂

[@danielyel6843]

Mike keep at this car. Don’t give up when these cars run right they are fantastic cars

[@Jsellers1965]

Your vehicle could have dirty fuel injectors, a damaged fuel pump, a blocked catalytic converter, a faulty mass airflow sensor, broken spark plugs, or even an accumulation of moisture

[@southernslipping4225]

Call Randy over to help you you always help him

[@laurensfundaytwl]

I'll believe that when I see it lol.

[@southernslipping4225]

@@laurensfundaytwl me to he always calls Mike and Santa’s work shop when he has something major to work on .. but never see him go and help them

[@bren70ssss94]

No hes too selfish .

[@geraldkiser6346]

Mike, not sure if your Volvo is equipped with one, but maybe a throttle position sensor? Seems your trans works fine if the engine is working properly. If it has the sensor, I’m sure there’s a DIY procedure to reset it. Good luck. Always enjoy your videos.

[@jeffmac3071]

Almost ready for detailing.

[@markjones6181]

Duck, duck, goose.......thanks for sharing Mike....Stay Up, Hard, and Healthy........🦢🦢🦆🐕🔥🔥❤️👍🏽💯.......,,,,,,an air pump needs vacuum 🔥💥💨

[@gregandrews573]

Check throttle body and pedal angle sensor.

[@dwanerusselburg7435]

Not a wasted day I like watching

[@rossfield8850]

Ahh good old Matthew’s Volvos site, been there many a time. Keep going Mike! Chasing the same hose issues on my Saab 95, just replaced all of them. My Volvo creaky suspension is driving me crazy tho!

[@danielklingberg8385]

Hello from sweden i whould clean the throttle body. Thats what makes it rev upp and down. If That does not work its boken. Its not a fuel issue.❤ Daniel

[@just4kicks950]

Ive had a few turbo cars that had bad turbo's that had surge problems. Not saying thats your deal. Still sounds like Vacum loss . I wish I had the answer Mike . Wish you all the best my friend 💯👍

[@462ANIMAL]

Good afternoon Mike !

[@Oyvind88]

Great video and work, hope you finding out off the problems😀💪

[@big_george_nyc]

Do a smoke test also

[@micahbush3877]

Great video. Don't give up you will get it

[@garyashdown5376]

🤔🤔🤔 I'll have a dig around at my end Mike, so don't lose the faith 😊. Gary 🇬🇧🇬🇧. PM you old chap

[@edwardmartinez9459]

Hey Mike Lola and Benzo will drive the wagon.

[@baitse7676]

I'd check all of the hose clamps for tightness. When it makes turbo boost, it could be blowing the metered air out of the hoses and then the mixture would be too rich to run properly. Also check the distributor cap, rotor, plugs and wires.

[@spidermannono]

Your transmission needs to be replaced that's why it keeps buckling I'm happy to see the Volvo running your channel is interesting I learn something new every day

[@PeterMitchell-s5t]

Yes transmission

[@kc0lif]

great job.

[@richroj]

that was very good Mike, I like the Volvo wagon 👍

[@tommyhall2768]

Hellow Mike good luck

[@mickthurston9883]

Good luck with the Volvo. Mick London

[@mtrgv]

Remove or keep in place the coolant temperature sensor. Then do an ohms and voltage checks with a multimeter. Check the table/chart etc to see if the sensor is operating within the specified ranges, if not remove and replace.

[@Frank-in-NY]

Just a guess, crack in the fuel line. I had a Olds 442 that I would lose power. Fuel line from the the Gas Tank had a crack, would suck air. I thanked my father for figuring it out.

[@jpcii]

I have seen these “surges” when I was working on my Audi S4 from bad throttle position sensor and when the throttle body needed “readaptation”.

[@WWRD1234]

Mike, I had my toy celica. Do that before and it was a mass air flow censor or it was a cut in the intake boot from the air cleaner to THE throttle body.

[@tomaslindgren3097]

My guess is the Idle control valve!

[@jazzycount]

It does idle a little high by the look of it

[@johnlabree6286]

We love the chatty duck.

[@bren70ssss94]

I love old volvos , my 940 is the only car i miss .

[@AutoAuctionRebuilds]

I bet it's a CVT transmission needing help. It's just like my Domino's Pizza car Mike!

[@edwardtc8129]

Hi Mike, love the content as always. I am by no means an expert but it’s only surging when it’s under load would make me think it’s something electronic. Do you think possibly one of the ecu is causing the problem? Either way if anyone can fix it you can. Look forward to more brilliant videos

[@bungeycord5971]

Smoke check your vacuum lines for more leaks then check mass airflow sensor and temperture coolant sensor.

[@StuartJones-hl4sw]

Collapsed cat converter? We had a ford mondeo where it used to bog down to idle if you floored it hard. The cat had collapsed and the innards were loose, under hard acceleration the internals would push back onto the exhaust exit. I also wouldnt do too much more headscratching until that other big pipe with the tie wrap is replaced

[@rick6084]

hey mike i think i can help you out, i am a mechanic. i have a few cheap ideas you can try. first and foremost, what people say about those 850 Turbos is very true, they are awesome cars and very easy to work on and modify them for alot more power. they are also pretty rare now, especially the 850 Turbo, i have a 1996 850R and i absolutely love it. I would HIGHLY reccomend that before you do anything else i would get some techron fuel treatment which will clean the injectors out really well and only add it to a quarter tank of gas that way it is twice as strong, and then i would do a seafoam treatment becuase i think a big part of your issue is that the valves and intake system probably has never been cleaned, those engines are amazing they dont build up a ton of carbon but any engine will build some up if it is not taken care of. if that doesnt help your issue then i would change the spark plugs to iridiums and also check how strong the coil for the spark plugs is, if that doesnt help then i would do the fuel filter as that has probaly never been changed either and possibly the fuel pump because it may be weak or wearing out, just please do not get rid of or give up on that car! trust me you will never let that thing go once you get it driving good, its a fast little car that has the perfect mixture of stiffness and softness to absorb the bumps. my very first car was a 1997 850 base model naturally aspirated and i got bored of it and stupidly sold it for $1300 with only 128k on it! ever since i sold it i have regretted selling it lol and now i finally found myself a nice 850R and it is awesome, especially at car shows everyone loves it. keep me updated on the repairs, send me a message if you want and we can exchance contact information and ill help you out!

[@MonkeyWrenchMike]

Thanks Rick! Appreciate the help!! Here’s my email - [e-mail]

[@smarternu]

I doubt electrical. Fuel mixture problems. Put a vacuum/boost gauge on it. It could be leaking anywhere, then check fuel pressure while operating. I suspect a pressure regulator that is being told to drop the pressure based on input that is not sustained....It thinks there is no boost when there is and it is cutting fuel when it needs more. Turbo's are very leak sensitive. Is there a TPS??? For sure test the TPS.

[@joshjones7296]

Mas airflow sensor mike, x

[@charlesrobinson-g7o]

I would check your tcv and cbv. Turbo control valve may need replaced, and compressor bypass valve diaphragm may have hole in it

[@ewaldmaas5790]

Mike I had a wrong install on my fuelpump, as soon as the car dove uphill it did not getting enough fuel.and air out of the tank mixed with fuel.put your car out of level on stands and test before you start dismantling or buying a lot of crab. It Creating a vaporlock

[@rafaelbetancourt3551]

Mike! is that Lola running in the background 9:26 :)

[@TheDude237]

Yes it is

[@clyderedalawton7425]

Hey Mike! The issue you are having with the Volvo, appears to be a defective throttle body. I hope this helps. God bless!

[@chadtrostle6234]

I’m not a Volvo tech but the bucking under load could be a misfire. Even though it hasn’t thrown a check engine light or code for it I’d check plugs, coils or for a bad spark plug wire. The high RPM at idle could be a sticky (IAC) idle air control.

[@kadinzaofelune]

Love Volvo's, don't fix it too quick I wanna chance at it.😊

[@southernslipping4225]

You have a boost leak check the pipe going to turbo

[@amadeo_serrano]

Have you done the mass cleaning? MAF sensor, throttle body etc? Another issue might be dirty injectors and/or fuel rail. Have you done the fuel filter(s)? If the latter is in order, be sure to blow out the fuel lines in case there is rust buildup or a collapsing hose.

[@trabertgraneau3323]

It looks like the high idling is a sign that the transmission is going bad. You should diagnose it just to make sure

[@alexanddebs]

Duck is the star!!!!!!

[@peterkwok9608]

Keep trying Mike. 😎😎👍👍

[@M_Phipps0520]

Idle air control, throttle position sensor for possible issues!

[@WWRD1234]

Thought of something else, mike idle positioning sensor

[@craighoskins1618]

Hey Mike what's your scan tool telling you

[@realstgaming4004]

It's a vacuum leak Mike the cars got one somewhere where it's going into limp home mode

[@albertag-be1eq]

Aflac didn't call to do tie in on video? Fuel filter or injectors, or change air filter. After 2001 Volvos started to get electrical, alarm problems.

[@jacksick8974]

It sounds like to me at your throttling positioning sensor. It might not be fuel related, but it might be electronic.

[@ranboranfarms7205]

Check The EGR It May Be Causing the problem

[@06VenomGT]

Not sure if that year of Volvo would have a throttle position sensor or an idle air control valve. My 1993 Chevy exhibited similar issues and it was these parts that caused the inconsistent idle.

[@someonejaw]

the throttle position sensor needs a relearn or a good clean possible maf sensor unplug the maf if it runs ok you got your problem

[@stevenhovinga6584]

Do you have a smoke machine you can hook up and see where all of your leaks are? I'm guessing you need to fix one problem at a time otherwise your going to be chasing your tail. Once you have all of your vacuum leaks fixed you might find that something that is controlled by vacuum is your actual issue. ✌

[@Devilfan9500]

The TURDO WAGON is having fitzz and Benzo was trying to tell you not to take her out I'm thinking Throttle position sensor if equiped

[@keithvallance219]

Throttle body Mike ?

[@mtrgv]

Your Duck needs another duck or a cat.

[@ronsautojax]

turbo control valve possible

[@jonathanbuffy3522]

I would say fuel related or throttle body or maybe a ignition coil

[@wrenchinwithgrandpa4586]

Have you cleaned the throttle body? I have an 05/2.5t- great engine, but as Volvo gets older they have vacuum/computer issues

[@HomelessAdventuresHD]

Mike check fuel pressure sensor and fuel injectors

[@colinhutchinson5282]

Hi Mike, is it with cold engine - seemed ok (or better) in your drive when warmed up ?

[@wrenchinwithgrandpa4586]

Have you checked your motor mounts?

[@ramonburgos2251]

Could be your roll over valve for your fuel line needs to be replaced

[@NeilM1]

Hi Mike, does it have a drive by wire throttle pedal? I had a car that would idle high and it was the fly by wire throttle, They replaced the pedal assembly and all was well.

[@TravisColeman-p8u]

If I was a betting man I would say fuel pump. My parents had a 1992 Cadillac DeVille and it was doing the same thing. They ended up replacing the fuel pump three times then it was good.

[@kentuckycornbread8502]

My friend had a camero bucking with erratic rpm’s and bucking. His turned out to be coil packs.

[@danielyel6843]

Have u looked at the eta module

[@jeffreyrush6308]

Could it be a fuel pump that doesn’t get enough gas going up a hill? Bad gas still?

[@kevintaylor7791]

Let's get some pet friendly fertilizer on that lawn. Lol

[@kevintaylor7791]

Call Elliot Alves

[@tamerhassan8847]

Hi Mike , please check gearbox it might be the issue

[@tonymolineiro554]

Fuel filter clogged under the door properly???

[@brad-gy2uq]

I'd say throttle position sensor maybe

[@ReviveAndDrive-mk1]

Bad throttle body or a bad idle speed sensor ??

[@juanbroughton3143]

my 2 cents, i would guess, clogged CAT

[@luigiaqua2263]

Make a reset on transmission.

[@ericgiroux320]

Had a 240 with a clogged in tank pickup screen. Don't know if that carries over to 700.

[@rjft7003]

Disconnect the air mass sensor or MAF. Most probably, that thing is long gone.

[@big_george_nyc]

Idle air control …. Or MAF

[@piris2007]

Hi Beloved One! Check PCV and CCV !

[@JustinKohl]

Check the fuel pressure?

[@FransvandenBergeMuziekschuur]

mass airflow sensor: kzbin.info/www/bejne/Y6auc5V9lK5piZo

[@robertogachoowiti6623]

Check the fuel pump relay

[@shawn041371]

I had a honda accord that was doing the same thing it ended up being the pcv valve

[@Anthonygaming02]

I like the video

[@derickthomas7435]

Bad plug wire or coil?

[@kenhagen7718]

Maybe Benzo needs another duck buddy

[@ardabilgutay4348]

Tips maybe what you think

[@bawjawmcgraw2232]

I would test the tps....

[@craighoskins1618]

Michael GMC Jimmy that would do that and they told me the torque converter was bad

[@mtrgv]

The oxygen sensor(s) are bad, replace them or the one. Good to go.
