BMW N63 misfire engine intake valves carbon cleaning inspecting the cause of the problem

Welcome to I.E. Euros.
Hi, I am Francisco.
We are a group of vehicle enthusiasts looking for Car meets, car shows, drag racing, roll racing, New cars, etc,..

after replacing the spark plugs on this N63, the misfire stay on cylinder number 7. the coil was good, the injector was good but still misfire.
the leads to a internal engine failure that can can by a low compression in the cylinder No. 7
by pressure testing the cylinder you can tell from where the leak is coming from. at the end, the leak was found in the intake valves.
but, that is a problem because, to really clean the intake valve you have to remove major components of the engine.
this could be a problem, but, there is solutions. using a intake valve cleaner can help as i showed in this video. so now you now, if a misfire never goes away, clean the intake valve
VERY IMPORTANT: MAKE SURE TO DELETE THE CODES OF THE COMPUTER BEFORE STARTING THE ENGINE OTHERWISE THE PEOBLEM WILL STAY PRESENT.

intake valve carbon build cleaning can help to fix problems like
drivetrain malfuntion errors
misfires
low power
low fuel economy
unstable idle
check engine light
smoke for tailpipe
We love performance vehicle
