Engine & DrivetrainDiscussions about the engine and drivetrain of your vehicle.
This is a discussion thread titled "best way to MAF + help incrase MPG", within the Engine & Drivetrain forum, part of the Technical & Vehicle Assistance Forums category.
i trying to get my gas milage up it is down in the 14's mostly high. but what is the best way of cleaning the MAF . and other ways to check if something need to be repalced or fixed its a stock 02 tundra. i have alredy looked at the air filter and it not that bad.
Remove the sensor and gently spray the electrodes with CDC Electrode cleaner (or like product). Allow to dry and re-install. Be careful. Don't use the oil type filters;TRD, etc.
In addition to what you mentioned, checking and maintaining your tire pressure is the first thing I would do to increase your gas mileage. I consistently get 18-19 mpg with mixed city/hwy driving with my V8. I keep my tires at 35 psi all around. Tires normally lose around 2 psi per month or more. Tire size can also play a role if you have huge tires. Other things you might consider: syn fuids, spark plugs every 30k, throttle body clean every 30k, fuel injector cleaner every 5-10k, keep drive train lubed for 4x4s, keeping highway speeds less than 70 mph.
[quote=apimpdad;885022]correct, but it is still going to get dirty over time, especially if you have a k&n filter that needs to be oiled, that oil can dirty up the MAF.[/quote
K&N oil on MAF...is URBAN MYTH.
For those that care to know hear the other side of the coin.
MAF's get dirty from the finer dust that gets through EVERY AIR FILTER OUT THERE. It is just dust. The dust really has no impact on its operation. It the oily soot build up from the crankcase blowby that ends up on the Heater portion of the MAF that is the real problem. And this varies by engine and type of use.
K&N oil is too viscous and tacky when dry to end up on the MAF. Period. A myth. Many other reason are found for failed MAF's
Some don't like the Cold air Intake designs of K&N's. Possibly justifyably so. The round turbin design of these non-OE shaped air filters are known to interfere with the OE A/F calibration of a non modded setup on some vehicles.
But the K&N drop in air filters are proven. They are lifetime and save money.
The only reason I have been using them for 17 years. And never a MAF issue
I'm not advcocating K&N's for all, but merely telling those not considering them because of a MAF issue's that this is the wrong reason to not consider them.
I use CRC MAF spray Cleaner. Cheap enough from any auto parts store. Yes, yu CAN use Electrical Contact spray from Radio shack. Which actually costs more money.
I saw one post that said they had an issue with a MAF and described using Brake Cleaner on his MAF. That's just crazy and irresponsible.
And, I'm sure that same member would blame a K&N filter for his failing MAF!!!
