Running Rich

[Chubs]

I am new to the Q world and a search came up with nothing. I have a 90 Q that has a very rough idle and ruch extremely. What would cause this rich condition? It will almost make you cry.

It will indeed. Did you try Infiniti Online Mechanic Forum in post bodies both current and archived? Might try leaky injectors also, and injecotr O rings

How are your engine's timing chain guides? If you don't know, read the Article in that Forum that refers to the problem before you ever start your car again.

moved to the online mechanic...

SOunds like you have an injector related problem either with your injectors or O rings...

can you give some history on the problem?
