Check Your Spark Plugs!!
#21
That was a very common problem on air cooled VWs... I am anal about using anti seize compound on the spark plug threads and not cross threading or or over torquing the plugs.... Over heating and detonation was the cause on VWs much of the time.. That wouldn't likely be what is happening on a Fit unless there was a code thrown that would have surely set off the CEL.

My 67 Beetle was the only car I ever had to coil a plug into.
I'm restoring my old [1970] Dual turntable for my son-in-law's Christmas present. Digging around I came up with the 'Instruction and Maintenance Manual' for that old bug. They warn about cross threading the plugs and say to '... tighten them firmly, but not over tight.' HA

If you didn't mind tearing down the engine about once a week or every 10 days, you could pull wheelies when shifting to 2nd..My beetle was as fast as my Fit up to 110 MPH at which time a rod bearing or 2 would spin or it would drop a valve If there was a a car like the old Beetle with a simple water cooled rear boxer engine without all of the crap that they pack into cars today and up dated brakes and suspension I'll bet they would sell like condoms outside a military base on Friday night.... A slightly worked over Goldwing motorcycle engine would be a great engine but a transmission with a real reverse and 6 or 8 forward speeds. The stock Goldwing has close to twice the power of the most powerful air cooled Beetles... Goldwings don't break either and as smooth running as an electric motor.

So I did it! No problems still have a misfire code going to my buddys house tomorrow to clear the codes because for some reasome disconnecting the battery for 6 hrs while I do the work isn't long enough to clear it, no engine roughness going to let it sit tonight

Do not change your plugs for anything else buy stock ones.
This engine is not a performance motor, it's a peppy economy engine.
Why put IK22s in this engine? keep your money, it's not called for this.
When people start messing with their OEM stuff, then you have issues!!!!!!!!!1

yep, you would mess the engine running colder plugs in colder weather,
run a can of sea form in your vehicle, use that tank completely before your change your oil.
cleans the carbon build up.
colder plugs are only needed on a heavily moded engine.
they will not increase your HP or mpg, that' s just BS marketing crap.
read the fine print, they would only increase your mpg or fuel economy if yuor engine is moded.

You pay the same price for the IK22 as you would for the Honda recommended Denzo plug.. So it is just a small power gain but it's free.. I have never had my car dyno tested but my Scan Gauge shows more ignition advance with the colder plugs.. It also shows more ignition advance when using premium fuel... The only part of the engine that is running cooler is the combustion chamber... The only car I haven't put colder plugs in is my wife's 2009 Forester.. It will be getting colder heat range plugs when the plugs are changed...... I may be in a situation where I will go one step colder if DSM talks me into changing to a smaller pulley and some other tricks to my supercharger...

Also, my factory plugs at 53,000 miles showed substantail signs of running too lean and too hot. That is common for modern cars, but gives more reason for changing often and with a heat range colder.

I am wondering if that's the cause of bad coil packs too. Its a shame there is no tuner available to rich-en it up in the mid range. Would a fuel regulator help with that problem by raising the fuel pressure so more fuel would be available? I remember having one on my sons B16 engine when we ran a 50 HP shot of Nitrous. I miss that motor, it revved to 9000 rpms.

As for the coil pack failures, that sadly seams to be common on every modern car. I blame it on poor manufacturing. There are aftermarket coil packs available for other cars that last much longer than the OEM ones. VW, Ford, GM, etc have all had their fair share of coil related problems. Coils are probably the most replaced engine component on modern cars.

These modern cars are designed to run lean and "lean is mean" when it comes to power production. The one step colder plug should solve the high combustion chamber temp. That is why they produce slightly more power.

Did you have the intake and exhaust on before you adjusted the valves and changed the plugs? Premium allows more timing advance in the mid range to produce more torque. Its denser in general compared to regular which allows more fuel to use at the same injector pulse and then it hits the o2 and it shows a perceived rich condition so fuel is pulled out and that is where your savings is. More torque using less gas.

I can't honestly say whether the plugs, valve adjustment, K&N, HFP muffler or a combo of any/all of them is to thank for my increased power and mileage. My wife and son were out of town which afforded me the opportunity to work on the car so everything was done at the same time. Not good for analytical analysis of parts, but fit my schedule.

Destroyed cylinder head
This issue happened to me yesterday. I drive a honda specifically because they shouldn't have a problem like this. 105k miles on a 2009 fit, factory spark plug ejected itself and took the threads in the head with it. I called a dealership and they said that this can't happen. Well. It did.
Would I have any luck calling Honda directly? Or is 105k just too far out of warranty?
I haven't been prompted by the meter to change the plugs yet but I was going to have it done anyway at next oil change.

So I bought a 2007 used honda fit and I think the same thing happened to my car... Forgive me I am NOT a person who is mechanically inclined, just wanting to save my car and looking for help wherever I can get it! Mechanic told me that a spark plug blew and burnt out the threading... tells me he needs to get a new helicoil but cant find one and if he cant then my only option is to buy a new engine (as the cost would be the same as trying to manufacture/machine in the threads due to the location). Wondering where you got your replacement helicoil, what the difference is between helicoil and timesert and if you have any advice for me? Any help is appreciated.

Besides. The oil started smelling like gas so who knows what is going on in there. He said they never removed the heads. So how do they drill it out and remove all the metal filings? I cringe.
I didn't have them price a used engine, but a new cylinder head was over $5000 with parts and labor. More than the whole car was worth.
Good luck. Someone has to know the size of the helicoil.
