Do I need MAF and fuel system cleaning from the dealership

Dear Scotty,

I just took our 2012 Toyota Camry SE for an oil change and tire rotation. It has about 107,000. They (Cabe Toyota) recommended getting the mass airflow sensor cleaning service ($89.95) and fuel induction and injection system service ($229.95).  I held off on those services.  Do I need to get them done? If so, can you refer us to someone in the Long Beach, CA, area who can perform them at a reasonable price?

We enjoy your videos.  Please keep up the great work!

Not a good idea to go to dealerships for service, especially on an older, out-of-warranty vehicle. Stay away from chain shops as well. Find a good independent mechanic in your area.

They're giving you the classic upsell. Unless you're having some kind of problem related to those parts there is no need for those "services". They serve mainly to drain your wallet.

The "MAF Sensor Service" will consist of spraying the sensor with a $10 can of cleaner. The "Fuel induction and injection system service" likely boils down to dumping a $10 bottle of Techron in the gas tank.

Thank you for your response. It is very much appreciated!

Not exactly.

Unless theres an issue I'd say you do not need them done.

I disagree. Doing this from time to time is a good way to keep the engine clean, and prevent those stubborn deposits

 

 

Thank you!

@mmj, I understand what you're saying but from my own experience I've run cars for decades and hundreds of thousands of miles without doing that kind of fuel system service and not had any problems. I'd say that if one wanted to do a preventative treatment, use a PEA based cleaner such as Techron in the tank once in a while, or the ATS "Carbon Clean" fuel system product that Scotty has talked about.

Well maybe your cars could have run better.
I don't think the in-tank cleaners are going to do as good of a job as the ones that flow concentrated solution directly to the injectors. I remember years ago induction service meant they also sprayed aerosol cleaner into the the throttle body as the engine ran. It cleaned your throttle, IAC valve, and intake runners of all the gunge from the PCV system.

I haven’t checked them out myself yet. Since they are too far for me to go regularly.

I am looking at The Toy Shop in Torrance and Cypress. They specialize in Toyotas and Lexus.  On one of their websites, for quotes, they just point you to RepairPal.

My Japanese auto shop I go to is called Japanese Auto Center, in North Hollywood. Pretty far for you and probably not worth the drive.

If you try the Toy Shop, let us know how it goes. 

Thank you for the recommendation!

Correction for the Noho location: Japanese Auto Tech Center, on Sherman Way. There is another one with a similar name.

If you aren’t getting any codes or check engine, you probably don’t need to clean the MAF. It’s also relatively DIY friendly, if you know your way around tools. (unless the MAF is in a funky location.)

Fuel Induction service is the biggest scam. It’s not even in the manual. The only reason you would need to do it is if you use bad fuel constantly, IMHO. 

I have never ever done a “Fuel Induction Service”.

Thank you!

as the video explains, it's needed for direct injected engines, and sometimes cars that are driven too infrequently.

Did they say why? Was the car running poorly or computer reporting bad data?

Sounds like its something they may recommend at a certain millage. Unless theres an issue I'd say you do not need them done.

Thank you for your response!
