Do not disturb the injectors! They damage easily and they will leak. The Common Rail injectors fitted to 1KD engines are fairly problematic and can cause significant engine damage if left unattended. He's thinking that the miss i'm feeling is actually fuel knock because one injector is streaming when it's cold. All engines are fitted with sensors which detect knock and retard the fuelling to prevent engine damage. Poor fuel quality and general wear and tear are not the only cause of injector failure, the newer type of injectors sometimes fail due to design problems. Alcohols can suppress knock both by cooling the charge because of its high latent heat of vaporization and because of its chemistry. Could be a partially blocked injector, when they are blocked it sounds like the big end is gone. However, a cylinder balance test (stopping spark or injector pulse at each cylinder one-at-a-time) is a good method in narrowing down a piston or rod knock to the problem cylinder.
