Injector(sticking) problem

[VQ20]

I seem to be having a problem with my injectors on my VQ35. They seem to be sticking open. Is there any way to rectify this problem???

i not sure which injector it is at yet as i haven't put a scanner on it as yet. Planning to pull all the injectors and change the plugs.

Reason i said they sticking open is because it is spitting raw gas out the exhaust. when we initially started the engine this was not happening. the engine idled and revved normal and smooth, when i took it out for a spin it came back misfiring and later i noticed behind the exhaust wet when i bent down i smelt raw gas.

Any help greatly appreciated.

OEM Injector internal spring failure is extremely rare...................no check engine light? Code?

It sounds like you might have a leaking lower o-ring on one of your injectors. It's happened to me twice. It could also be a bad fuel (rail) regulator or many dead injectors but I'm thinking o-ring first. At this point you don't want to hydrolock the engine and bend a rod, or catch your Q and the neighborhood on fire so be careful.

You're on the right track by removing the plugs. If it's a leaker a bank (left or right) of plugs will be soaked in fuel. Done any injector replacements lately? This may help narrow it down. Good luck.

easiest way to check nad see if its an O ring woudl be to hook your fuel pressure gauge up to the fuel rail, prime the fuel pump and see if you get a pressure drop..

Ohm your injectors and then replace O rings as necessary. 95% sure this will correct your problem.
