I have cylender that is. Not firing and when taking ng off heads #1 was like ne

ONE of the pistons looks like new > Coolant leaking into combustion chamber > failed head gasket or crack in cylinder head .... Excessive fuel delevery > injector issue .... Low compression OR no spark > not burning fuel off piston.... More testing should have been done 'before' cylinder head removal to determine exact cause of misfire! Suggest having qualified personnel come have a look at it for you... Good luck!

Pushroad is right, there are many things that can cause a misfire, the most common that we have seen on Toyotas are burnt valves, but mechanical and electrical diagnosis has to be performed before you jump the gun and pull the head. Fabian
