According to the Unofficial Holden Commodore Archive for VZ, all engine variants have electronic sequential fuel injection.Port Fuel Injection.
According to the Unofficial Holden Commodore Archive for VZ, all engine variants have electronic sequential fuel injection.
The above archive doesn't mention engine RPO codes, nor does it specify that fuel is injected into each intake port.
But port injection and sequential fuel injection are not the same thing according to this article.
So, it may be that calling it port injection is wrong
VZ does not have direct injection.I like this article. I know from working on them that the alloytec has 6 injectors. If the article is indeed correct then the engine is a MPFI with SIDI. How did you find it?
