Re: Extreme rich condition
That's at good MAP sensor signal at idle. The sensor is requesting idle fueling.
How does the engine run when you drive the car? It should run smoothly when accelerating. Even if it is running rich the engine should run smoothly but might be down on power because there is too much fuel. I'm wondering if there is a misfire?
Are the spark plugs carboned from the old fuel injectors? You don't need to get a new set of plugs if they are just dirty. The tips can be cleaned by spraying them with carburetor cleaner, letting them dry. Then heating them with a Propane torch.
