The other neglected, is the air intake hose, if it leaks/torn it tends to absorb the hot air from the engine compartment which also has less oxygen/expanded air and leads to reduced mileage/high consumption. Check your air intake hose too. I learned it the hard way.

because he's right. I'm from a family of engineers (we don't agree on anything politically), but we all agree when it comes to German cars and German Engineering. Independently (since we'v never agreed in the past) we've all concluded a long time ago that "German Engineering" is a Ridiculous marketing slogan, and like all marketing slogans, a complete lie or hugely overrated and exaggerated. Stuff engineered in Germany is often below average, often over engineered or under engineered, often weird, rigid and poorly thought through and expensive because it's inefficiently produced. Japanese products, on the other hand, are almost perfectly optimized between cost and quality.

Hi Scotty. Last fall, I bought a 2015 Toyota Corolla Eco plus Le. It had 75,000 miles on it, and it was in great shape. It came with free services for the life of the vehicle at the dealership, so I had the oil changed four times at the dealership and put 20,000 miles on it since I bought it. 3,400 mi into the last oil change, it threw a code, p2647 "A" rocker arm stuck on in Bank One. Since I haven't looked under the hood since I bought it, I decided to check under the hood. The plastic shroud that covers the valve cover had an oil slick on top of it with bugs and dust collecting on it. I decided to pop it off and clean everything up. I checked the air filter and it was as dirty as if it were not changed in 20,000 miles. Upon discovering this I decided to do a full service myself. The the edges of the oil filter cap were rounded and the retainer clip was missing. It was as if some kid didn't have the right tool and strip the oil filter cap and decided to leave it instead of changing it. I used a piece of paper inserted inside the oil filter wrench so that the wrench would grip onto the filter cap. This worked great and the filter came right off, however the filter was the blackest filter I've ever seen. Sure enough, the oil was black and full of sludge. Since the engine oil was so dirty, I decided to change the spark plugs as well. It had 95,000 miles on it anyway and that's when the maintenance schedule said I should change the spark plugs. Two of the plugs were dark and fouled. I hesitantly put mobile one high mileage 0-20 full synthetic oil in it, knowing that the swellers in the new oil would prevent me from using any other oil for the life of the vehicle, but since my engine was dirty I figured it wouldn't hurt to use mobile one full synthetic. I even changed the actuator solenoid that was throwing the code. After changing the oil, the oil filter, the air filter, and the spark plugs, along with the new actuator, the code cleared itself. The engine immediately sounded like it was running more smooth. It hasn't thrown the code since. Needless to say I will never bring it into the dealership for the free maintenance again, I will just do the maintenance myself. Do you have any advice for me pertaining to which other parts I should inspect or change?

[@kayaaruaqyukonkingenterpri9992]

On a side note, my auto start isn't working right. It turns over, but is either too rich, or too lean to start. It makes a knocking sound and fails to start. Then I have to wait about five minutes before I try to start it again with the key, and it works. I'm stumped. Winter is coming, and I live in Alaska. Auto start will be a very desired luxury, then.

Good timing on this. I just washed and re-oiled mine today. That came as part of the oil change, check all the fluids, and a lube.

[@stanleydenning]

I have a 1995 Ford Ranger with a 3.0 L V-6. I bout it used and it ran OK. One day, on a whim, I decided to do some maintenance. I changed the air filter, cleaned the mass airflow sensor, cleaned the idle air valve, and replaced a cracked vacuum hose. OMG! What a difference. A rough guess... 20% more horsepower and 15% better fuel mileage.

[@SlikLizrd]

Most of your gains were probably the result of replacing the bad Vacuum Hose. The NEXT time you buy a "new" car, do those things right away -- and start saving IMMEDIATELY !! 😁

[@BixbyConsequence]

Hold your K&N up to the light and check out the size of the holes in that media. Not worth the miniscule HP gain at the top end. Your engine spends a heck of a lot more time suffering from the reduced filtration than it does taking advantage of a miniscule HP gain at wide open throttle.

AEM reusable filters don’t use oil, assuming you used the K&N filters, which is what led to your problem. Likely the MAF sensor got oil on it over time. If you want to keep using the K&N, you would need to clean the MAF sensor with MAF cleaner spray periodically to avoid issues.

[@Johnslist]

. @StandAloneState If the MAF gets fouled it throws a code, I did that once, but I think my cat got fouled from a misfire condition and bad A/F sensor. I may just stick to paper to remove that variable. I was told once that cleaning the MAF too often is bad - just stick with OEM...

[@StandAloneState]

@@Johnslist didn’t know that, but it makes sense. If you can keep cleaning the MAF sensor then the computer won’t have to keep adjusting air ratios all the time and messing with running lean/rich

[@johnnyvegas5681]

Scotty...I really need a video titled something like "if you do this (or buy this) you're super smart!" I need some positive reinforcement these days Scott ;

[@teambenjamin1]

🤔 A dirty air filter will lower the power, but I’m pretty confident that the O2 and maf sensors will detect less oxygen and airflow. The computer will adjust the fuel air ratio automatically so it won’t run rich or get less gas mileage. Of course that’s if you have a fuel injected car, which most are nowadays.

[@michaelthomas366]

Good job at narration Scotty! More documentary style clips would be good.

[@craigs7069]

Yeah I had a grease rag get sucked up in my intake on a turbocharged car. Couldn't figure out why it had no power. Then it made it up the tube and covered the filter before I figured it out

[@martyk1156]

Vehicles with mass air flow sensors compensate for restricted air filters keeping optimized stochiometric fuel mixture. Fuel milage will drop on vehicles with carbs. Keep in mind many high flow filters do not filter fine dust.

What do you think of a 2001 Silverado 1500 5.7 v8 with 90000 miles on it

[@234234234werrrrrrr]

I put 6 air filters on mine for a 300hp boost

[@mikebelcher5111]

With that low of miles probably a great truck . Most came with a 5.3 (327)or a occasional 5.0 (305)the 5.7 (350) I feel is better than the 5.3 .my dad's has 300k miles original engine and tranny the main issue with these trucks is body rust

[@SlowRiderDucati]

I have a 2002 Chevy 1500 LT Z71 with 450,000 miles and still runs great. I bought brand new. Still starts and runs like new. I change oil every 5k miles. Also front wheel bearings replaced at 150k miles, and one alternator, and one hot water intake connector into the cabin heat exchanger, brakes, tires. So I would buy as the truck is basically brand new with less than 100k miles. As long as it starts easy, doesn't knock, blow smoke or have any tranny clunks, or funky shifts. The 5.3 liter Vortex V8 will run forever. I live up near lake Tahoe and it is the best snow four wheel drive ever. I never have gotten stuck and always pull out the Jeeps, fords, and other brands. I've driven through overhead snow drifts for hours on the dark desert roads of Nevada for 100s of mikes at a time and never got stuck.

[@MarcPiery]

A 2001 with a 5.7? I only remember them with the 4.8, 5.3, 6.0, 8.1, and the 6.6 Duramax. As far as I remember, they only used the 5.7 until 1999. My 2001 Suburban has the 5.3. Go into your glove compartment, and look at the options sticker. Go through all of the codes listed. One of them will be the engine code for the engine that the truck came with.

[@nevergiveup7502]

Next to changing the engine oil and transmission oil. Changing the air filter is the easiest thing to do on a vehicle.

[@raulmojica2253]

What a Great! Quality Video. Very Good presentation. Hats Off Scotty!!!

[@philguzman6932]

I just changed the air filter in my truck last week. My truck was running a little off. Opened up the box, pulled the filter out, it was black. But, there were 2 surprises waiting in the air box for me 1. A mouse nest and 2. A piece of baby mouse jerky. Am I glad I was wearing some nitrile gloves.

[@ep9217]

Mr. Scotty Kilmer hello. I am trying to program a brand new replacement key fob for my 2001 Chevy Tahoe. As mentioned the key fob is brand new, with brand new working batteries. I have followed/repeated the entire insert key, hold down unlock button, turn ignition off/on twice, wait for the lock to cycle, press and hold lock/unlock on fob simultaneously. But the lock never cycles therefore the Tahoe never enters programming mode. As a side note, I know that the locks are capable of cycling. Because when I pull and hold the bright light lever while cycling the key twice to program my desired door lock/unlock sequence the locks will actually cycle, the same way that they should when programming the key fobs. Can you please share some troubleshooting steps that might help me diagnose why my Tahoe won't enter programming mode so that I can program my new key fobs? Thank you.

[@markreams3192]

I have a 2020 Tacoma. Third gen Tacoma’s are known for sluggish throttle response at light throttle application. Part of this is due to the part time Atkinson cycle. Toyota uses this to increase gas mileage. However I believe it’s also due to a very restrictive air filter, even when new. This can be partially solved by installing a TRD cold air intake from Toyota for $400. Way too much money. Instead I installed a K&N 57 FIPK cold air intake at less than half the cost. It’s simply a kit that replaces the stock filter using the stock air box and the air tube leading from the air box to the throttle body. The stock air box is a cold air intake and the K&N tube eliminates the resonator box giving a smoother air flow to the throttle body. This system noticeably improved light application throttle response. K&N tested the intake and claims an increase of almost 11hp and 9 lb ft of torque. By the way the engine responds I believe it also flattened the torque curve. I subsequently installed a TRD exhaust which further increased power output. It runs and sounds very good. It also tows better! It doesn’t totally bypass the Atkinson cycle but does supply more fuel air mixture at lower RPMs.

[@markreams3192]

@Mild Child Atkinson cycle is great for fuel mileage but bad for power. With variable valve timing the engine will go back to Otto cycle when you get on it. When it does it almost feels like turbo lag. There’s a sudden increase in power. This design is to meet CAFE requirements. Toyota sells 250,000 Tacoma’s a year which effects their Corporate Average Fuel Economy. It actually gets the best mileage of any V6 vehicles I’ve ever owned

[@scottthompson305]

Have a k&n filter on my 07 h3. Oil residue from filter causes frequent maf sensor cleanings

[@hotrodray6802]

Fuel mixture is not affected by dirty air filters. THINK. What do oxygen sensors do?

[@CWJameson]

Scotty what air filter do you like best ? Paper or kn style ?

[@michaelb.8953]

He did a video on this quite a while ago and he prefers paper as he didn't have too many positive things to say about K&N air filters.

[@boobtubeakatv1296]

Scotty likes what ever the manufacture originally put in it... Usually paper & blueprints

[@johnd4348]

Yes I guy brought in his air filter from a 1968 ford truck. First time its ever been changed. in 31 years. Is that ok. He said it was running a little sluggish.

[@rudygeorgiamulesandcountry1594]

Yeah, ... I was having MPG problems in a V8 Chevy van. Naturally the first thing I checked was the air filter, it look brand new. N0T being able to pin point anything else I took the vehicle to my mechanic. Much to my suprise when I picked the truck up I was shown a huge wad of pine needles that some rodent had deposited inside the tube leading from the air fi.ter to the fresh cool air outside the grill.

Hey Scotty, I own a 2015 Jeep Cherokee Limited edition with a 3.2 L V6 engine. I have owned the car for a number of years and have put about 40,000 miles on it (it now has about 70,000 miles on it ). I’ve had no work done on it after several years! Why do you have such distaste for the new Fiat Chrysler Jeeps?

[@TAKIZAWAYAMASHITA]

because they dont last like they should, the newer ones should last 200+ thousand miles mostly trouble free but that doesnt happen. people have seen those cars break as early as 70,000miles which is unacceptable

[@peterd2587]

I bought a used jeep JK once ran great, got under the hood and air filter box was packed with a packrat nest, I mean packed! Cleaned it out, no change

Scotty is tops I enjoy listening to him !

[@thomaswirth5226]

I let my truck sit outside for a month. Then I replaced the alternator, underneath the air filter housing. There was a mouse nest in the air filter housing and mice had chewed the ends off some of the pleats of the air filter, making long, narrow holes through the filter element. Filters may have some resistance to mice chewing, but it's not foolproof.

[@taneshanottanesha5456]

Hey I have a question. Did it have any issues before you fixed it up? Like surging or acting like it's trying to quit? I have a '04 impala that has this issue, but the air filter was clean. The engine or areas around the sensors are caked with dirt. Could a mice have chewed through a hose or plastic that may have caused the contents of the air intake to entire the engine?

[@SixMonthsIn]

Scotty, I have a 2007 F350 DRW truck with the 6.8L engine that runs great and has plenty of life left in it (178k miles). However, when I do a warm start (like stopping and going into a store and coming back out) the truck hesitates for a few seconds when I first take off like like it is not getting enough fuel (or too much). If I let it idle for a few seconds more, it runs just fine when taking off. It is only for a few seconds that it does this. Is this a leaky injector? I have checked the fuel pressure immediately after I shut off the engine and it drops to 0 PSI immediately, but my truck has a returnless fuel system. It is NOT hard to start and fires right up after a crank or two. What do you think this is?

[@bubbaho-tep4975]

My Mustang GT has the air filter canister ported outside the engine compartment. One day after leaving work the car just died and would not start. No CEL. Turns out a plastic shopping bag was sucked up into the cold-air tube and vacuum formed around the filter so tight is nearly crushed it.

[@condimentking14]

Yes I had a weird one one time well I used to have a 1990 Toyota 4Runner with the 3.0 otherwise there was a 3-point slow well one time change the air filter I found a peanut m&m in the intake system I don't remember what color it was but I kind of want to know something how did that get there 🤔 I also remember as a kid my great-grandfather had a 1970 Buick LeSabre with a 455 he used to blow the air filter out with a leaf blower and then reinstall it and I didn't know if the time that was a good idea but you know now looking back at it I go wow that's probably not something you should do

I once bought an old Ford Courier at an estate auction. Of course, I was going to trailer it home, but who can resist trying to start an old engine? So we pulled the fuel line off, hooked up a gallon jug of gas to gravity flow, in case the pump was bad, and gave it a go. It fired off with the hot battery from my truck, but puked and gagged like a Shriner with a hangover. The distributor was loose, but no position helped it. And after my brother got juiced by the coil twice, we determined we had fire to the plugs. That's when we took the top of the breather off, expecting to find a dirt dobber nest. We instead found someone had substituted foam rubber for a filter, and with it having no stiffened borders, that foam was now stuck in the top of the carb in a big was. It was partially melted when we pried it out, which was good as the chunks were too big to do much except smother the engine. I later found the carb didn't have a gasket at all, so it must have sucked enough that way to run a few minutes. But, a rebuilt carb and a junkyard radiator later, that little booger run like the piece of junk it was intended to be. (I like Ford's, for the most part, but that thing wasn't even an improvement on a Subaru Brat.)
