Hi! Try to search but no find
Question is
How start the coolant intrusion??
Two years ago my coolant just dissapear
No white smoke
No problem of driving
Nothing
Refill and never again happen
Nowdays after a bad spark change i star experience misfire the original sparks wasnt wet
The bad ones wasnt wet
I think the cause of.misfire was carbon buildup cause the bad sparks and the originsl ones come with carbon on the tip
And i read that misfire almost always was in cylinder 2-3
My misfire is in 4
Check coils and spark and it doesnt come wet or anything in the exhaust or bubbles in the reservoir of coolant
Repeat the coolant doesnt low the level
Almost all days checked after read about coolant intrusion
So..how start..anyway that i can check this q dissambly.all engine??
Cause i think that once happen...two years after the refill it will happen again or not?
Or what??
Cause i think if it was leaking or.something i get white smoke in the exhaust or not??
Like i said two years and the level doesnt drop again
Sorry if you dont understand this not native english

Updates...
Do heavy load...and no misfire just one a little Like 1sec not like the 20secs and many before
So...i think is solved and its just cleaning the cylinder and the chamber caused by the bad plug
So will run another liquimoly cleaner
The car go from 60kmh to 140 without issues
And will try to check the carbon buildup...
Thanks for your help

Update:
Yes..still misfire not so often but still happen
Before notice the misfire i get the P2196 code
And remember last year i got the o2 sensor code
So..some research says p2196 could.be the evap.valve and im.getting the fart from tank so...
I Will change that valve
Do you know any way to test the o2 sensor with forscan?
Thanks

They can get slow to respond to mixture changes as they age. You could try monitoring the voltage in ForScan and make sure it responds immediately to the accelerator being floored and released (assuming there's no delay in ForScan responding....)Do you know any way to test the o2 sensor with forscan?
Or, perhaps just replace it as they don't last forever.

Dude i have a real rare question here
Today go to other mechanic to do some question about cost of diagnostic the problems
And in some test he do
He remove the connector from coil 3 and then plug in again and the car take about 30 seconds to stabilize
then remove the other coils and the car take less than 5 seconds
so here the questin is!!!
could another cilynder misfiring cause the code on other?
i mean in the case of
coil 3 fail cause a Cylinder 4 code??
i have problem trying to redact this sorry
not native
my car shows the cylinder 4 misfiring
