Just removed Hydrocarbon filter

Believe me my friend...I've been there. I have been to heck and back the past few years. I'm learning to appreciate the small things in life more than ever.

I've has three major spine surgeries, three left leg rebuilds, and a failing kidney and liver and subsequent gall bladder removal and parts of my stomach and liver taken out this past year.

To top it all off, my cousin and best friend (everyone thought we were twin brothers having grown up together and left to attend college together and then stayed in Utah after to work) was diagnosed with pancreatic cancer the last week of July. By October 1st it had moved to stage 4 and he passed on October 24th. I made sure he got to spend his last 90 days with me after the diagnosis and I and my children learned a lot about gratitude and love.

He's gone now, but it was brutal and someday we are all zombies.

My point is that I guess I feel your pain and me here if any of you ever need to talk: working on the truck keeps the brain occupied; but let's keep it to a minimum so we aren't gold playing the engine bay! :)

We are all looking for the small victories that carry us through the days and I'm so thankful for them and the great people on this board. I look forward to getting more active now that I'm driving a 4R v8 sport again ! Yeeehaw!

Keep fighting! As you can see I made things sound like life is humming right along, but there has been some seriously scary and painful crap going on. Just look at those small victories and latch on to them. If you need something to do find a local working on a project and chip in time and expertise and maybe a tool or two. Make a new friend and make the hard days rly by faster!

Keep up the great attitudes and tons of info. It's great to see you all hopefully soon we will be trading some truly life changing tips for our trucks and for each other!

Thanks for having me back. Sorry the dumb questions will flow again soon, but you supahstars know the 4R like I know pizza. :)
 
Sorry about all of the terrible misspellings in my previous post. Now I can see it barely made sense. I was typing it on my phone without my glasses on. Sometimes I wonder if autocorrect is just there to make us all look stupid! :)

Thanks again for all of you. I hope you've had a great Christmas/Holiday Season. We are a Christmas family, and have adopted aspects of Kwanzaa over the years due to the manner in which my wife's family (and of course my children) were originally 'transported' into the state of Georgia to work on a plantation. Try explaining that situation to your eleven year old son without seeing the clear anger and sheer bafflement in his eyes for why he ended up here. H'e glad to be here and loves being an American, but he just can't figure it out, and frankly I can't either, nor can I justify it for one second and it is quite embarrassing to say the least, but at least I can say, "But I got to meet your hot mom, marry her, and have the two most amazing kids on earth, sowe're doing alright, right?!" He used to agree... now he just asks more questions.

So hopefully I can get him more focused on the mileage numbers on my T4R so I don't have to keep justifying unjustifiable history when our rides get long and boring. ;)
 
No way in bleepin he!! you got 22mpg going 80-85 with the V8.


The absolute best I can get with my V8 -- stock airbox still has the HC filter -- all filters/fluids/plugs etc. fresh as a daisy, no extra racks etc. dangling off the car, on a pool-table flat highway at 70 mph, using 87 octane in the summer, is 19.7 mpg. This is based on actual consumption and actual mileage.
 
DING DING DING!!!! We have a winner!!!! :iagree:

If you INCREASE AIR, the MAS (Mass Airflow Sensor) MUST INCREASE FUEL!!!!!

Otherwise, you're running TOO LEAN which means TOO HOT and things will begin to fail.....warped heads, blown head gaskets, etc. The MAF will NOT allow that. It will just increase the FUEL FLOW to match the AIR FLOW for the correct FUEL/AIR ratio.

The ONLY result you MIGHT see is the INCREASE THROTTLE RESPONSE. That's because you are allowing MORE AIR AND MORE FUEL.



Good Mother of God this is an ignorant statement. Yes, the MAF and ECU will obviously increase fuel if there's more air. But there is, at the same time, more _power_. Which is the point of the exercise. omfg
 
Lets be honest here... First of all, hydrocarbons are unburned fuel. They can be produced by incomplete combustion and expelled out of the exhaust. They are also produced by raw fuel, which is the exact reason that Toyota engineers put a hydrocarbon filter on the intake of the 4Runner. The idea is to filter hydrocarbons produced by the raw fuel instead of letting them vent to the atmosphere.

To say (or think) that "zero fumes" (hydrocarbons) are produced is completely wrong. Do you really think Toyota would waste money on engineering and then installing filters to capture hydrocarbons that don't exist in the first place? Come on, lets keep it real.

But of course it is your choice whether or not to remove the filter, and I don't really care either way. But please don't try to convince everyone else that the filter does nothing and that removing it will make no difference when it comes to venting hydrocarbons into our atmosphere. I'm glad that you're happy with your mod. I'll be keeping mine in place.

So what? The unburnt fuel is real but let it go into the atmosphere. Makes little difference.
 
Do I dare resurrect this thread? :) I just removed mine and wanted to see a difference, but I don't have enough data from before the removal to track it. The only thing that really annoyed me is the serviceability. If they made this filter serviceable, I'd probably keep it.
