Good morning. Please I need help on my 2007 Hyundai Elantra 2007 rough idle and poor acceleration issue . At times it works perfectly. The last scan showed oxygen sensor failure and we have replaced that all to no avail. Replaced all plugs, flushed all nozzles, checked fuel pump, none seems working. What I noticed is that the problem occurred most when the car battery is disconnected. Although it happens most times without disconnecting the battery

Service the Automatic Choke on the throttle body or replace entire throttle body (injector mouth)

Snap out of this bullshit
The Bleep dis long dumb ass epistles for foom
Its a free site

Now we all know the real "Dumb" and the "Bilullshit". I've just reduced the long epistle to two words. I hope one is enough to make u wise. Yes its a free site but not where we are supposed to be insulting each other and calling names. Lets maintain the team spirit. ONE LOVE.

RoadMozart:
One chilled Goldberg for you boss🙌

Thanks bro. I really need it.

Listen to me and listen real good. Never trust anyone aside myself. Mechanics are thieves,rewires are ticking timing bomb,while panels are destined for hell. Get yourself a new engine and at least rest for another 6 to 8months.if u keep up with diff fools advice here or keep going to a mechanic. U are gonna get scammed,and they will scatter your engine till brainbox level.scrap that engine and get a toks .now u cant tell between what a single cell and doubl3 cell is. A double cell radiator for a 4plug engine.hahahahaha. see how u wan use all your money buy fuel, mechanics and quacks know reality but want you to keep coning back,so they extort u. No worry ...continue. hahahahaha.

It's quite unfortunate that people that make defamatory comments like these exist here and he even laughed about it.

Not a very great tribute but it does have some elements of truth. I am a mechanic and I'm extremely proud of my profession because I believe I have all the knowledge and experience to handle any automobile issue hence my background as a qualified and certified Automobile Engineer with experience that spans three continents and over 37 years.

Thus said, yes we do have many unscrupulous elements parading themselves as Auto Technicians. Many of them dont have proper workshops or convenient work premises. They dont have adequate tools or equipments for the jobs they do. Very rudimentary set ups and they without hesitation will recklessly rip apart any unsuspecting victim and fleece them as an appended part of their trade.
However, many of such victims usually seek cheap labour and minimal costs to parts (usually fake or substandard) to effect repairs on their cars believing all should be well. Familiarity and fairness on the first visit is the lure and over time becomes breach in trust, negligence and ignorance not forgetting incompetence. But thats what you get when you want cheap, unprofessional and unskilled labor. Most of these mechanics are illiterate to the discipline and ethics required for these tasks which are mostly complicated and requires a good level of knowledge of the operational principles of the Internal Combustion engine and the all its associated components before establishing a service provision platform. So you'll find out that most car owners are more educated via physical
shadowed interactions and information on the Internet than the individual handling a repair job on their behalf.

The frustration is that most car owners don't want to get their hands dirty and most likely don't have the mechanical temerity to process the job hands-on or may possibly be a total layperson. That may also be ego attributed but thats the price you pay.


Back to terra firma, I have always maintained integrity and honesty as watchwords in my own professional conducts and have exhibited and conducted various challenging jobs in car repairs in 37 years of my career both home here in Nigeria and abroad in the Europe and the Middle East and I do know that certain jobs requires well grounded knowledge of car mechanics and particularly specific to the make and model of any car before ANY kind of repairs is attempted.

I as a professional have had my fingers burnt and disappointed by many third party associations and I have learned the hard way especially here in the climes of Nigeria. What I know now and understand is quite unbelievable and the dark side for those who don't know is treacherous and uncharted but I do make efforts in educating and keeping my clients informed on every single process of the repairs from diagnostics to completion. Still best to approach with caution by verifying content and capacity before engagement.



Now for the poster of this post, may I inform you that Gazzuzz is not a thief. Kingreign is not a thief. Sienna is not a thief. Ikenna is not a thief and my humble self The Car-doctor of Nairaland, I AM NOT A THIEF. We are all professionals in this industry and I believe we represent and eschew great value on this forum so I see this as an insult to our personalities and more importantly our integrity when we get labeled and listed among the likes of those "quacks" as you rightly called them whom you may have fallen victim to.

I am seriously demanding an apology from you the poster @2cribz for the derogatory remarks and demeaning statements in this post on behalf of all Nairalanders and moderators especially here on the Car Talk forum.

If I could ask you a question from the advice that you gave. It will go thus:

WHO WILL FIT IN THE REPLACEMENT ENGINE YOU ADVISED?

WHO?

Please lets respect ourselves here and avoid putting unnecessary fear into the hearts and minds of those who are passionate and reliant on our honest contributions on this forum.

Thank you.

Who buys these things?

The list is endless

ZEPHYREN:
First time buyer, would appreciate advice.

For any appropriate advice on issues like this, always indicate engine size. One we know is a V6 and thats the Lexus but whats the Sonata engine size? Go for the Sonata wether V6 or Straight 4 because its a 2016. A little bit of luxury will be lost from the Lexus but a full option Sonata is more of a match.

Simple. Its a MERCEDES

Always go for Synthetic if you can afford it. Best for modern engines.

This post is for those who have DIY scanners and want to check the performance of their vehicles Oxygen sensors and how to Identify the Symptoms of it's malfunction or performance issues.

Oxygen sensor is crucial for emission regulation and engine efficiency. This device monitors oxygen levels in exhaust gases, helping to adjust the air-fuel mixture for optimal engine operation.

Oxygen sensor before catalyst:
Also known as the primary sensor or topwater, it’s located in the exhaust manifold, before the catalyst. Its function is to measure oxygen content immediately upon exiting the engine, influencing the mix of air and fuel.

Operation:
Oxygen sensors use a zirconium dioxide element that generates volts depending on the difference in oxygen between exhaust gases and outdoor air.
️️
Voltage Range:
Oscillation between 0.1V and 0.9V. A low voltage (0.1V) indicates a poor mixture (excess oxygen), while a high (0.9V) suggests a rich mixture (less oxygen).

Oscillation:
The signal must oscillate several times per second. A low frequency could be an indicator of wear and tear or the presence of contaminants.

Rear catalyst oxygen sensor:
This sensor, also called downstream or secondary, is located behind the catalyst. Their primary task is to monitor the efficiency of the catalyst, comparing oxygen levels before and after the catalytic conversion. It operates in a similar way to the primary sensor, generating a voltage based on the oxygen level.

Voltage Range:
It is more stable, usually around 0.45V when the catalyst is working properly.

Signal comparison: If the signals of this sensor match those of the previous sensor, it may mean a failure in the catalyst, which activates the Check Engine light.

I took my car for flash painting and left it with the painter in his carrage. After 5 days, painter is telling me my car is not selecting gear. Car cannot move front or back. He checked and discovered oil leaked from under the car and gear oil has finished.
We refill the gear oil and the car can now move front and back , and selecting now. No sign of leakage now.
So please what is the possible cause of the leakage and hope gearbox is not affected now?

Its important to note on what type of transmission oil that was used for the service. Wrong type or wrong transmission oil could result to transmission failure.

Hello, please I need help with my car,

My car was flooded last year and it affected my gear. I took it to a gear specialist and it was fixed and started working.

Last month I noticed that when I am increasing my speed from 40 to 60, my car does not respond immediately. It drags or jerks.

I took it back to my mechanic and I was told there was issues switching from gear 2 to gear 3 and that it skips gear 3 and goes to gear 4.

What could be the cause of this and what next steps should I take.

Car Model - 2011 Camry
Gear - 22 pin

What type of transmission oil did they use for the service?

I thought people only fought over land. Which one be fight over pond again?

Hmmm

Are they still discussing state development? I thought OUK has done everything.

Dammmmnnn

Lagos has enough food already.

It was obviously a political statement

May God help this country

Who wants to invest when there's been so much demolitions of tourist spots.

And still dropping.

They have capacity to recover more than that.

Why not 10 things?

That means u went to Government College Boarding School Birmingham.

This man still dey?

Should we start running?

Good move

No place like home
