Function of a ECG Valve?

Answer:

There's no such thing as an ECG valve on any automobile. You're probably referring to the EGR (Exhaust Gas Recirculation) valve. It's purpose is to pipe a little bit of the exhaust gases back into your cylinders at higher RPMs to both promote cleaner emissions and to cool down the combustion chambers to help prevent knocking and pinging. However, in time an EGR valve can eventually get clogged with carbon which can cause it to get stuck open, which would cause an excessively lean condition during idle and can cause the car to stall. It then needs to be either cleaned (with plenty of carburetor cleaner spray) or replaced. I generally wouldn't say that a defective EGR would make a car unsafe, unless perhaps there's a big crack in it and exhaust gases (carbon monoxide) are leaking into the engine compartment/vents. I would, though, take a little extra care when crossing railroad tracks or turning in front of fast-moving traffic. Stalling there could possibly turn you into a coroner's curiosity.
Ecg Valve
ECG/EKG stands for electrocardiogram. Its a way to see your heart beat pretty much. There are little waves on a screen that come up and it shows how strong or weak your heart is, and how fast or slow it beats. And what your mitral valve does is open and close to allow oxygen rich blood into your left ventrical.
