Black Spark plugs and rich afr

Recommended Posts

Hi, my car is running really bad atm. 

It starts well. But idle is rich(Black plugs) and 10afr on brand new aem wideband   and cant accelerate smoothly. In one Word its undrivable.

My attention is on the map sensor.

I get 1.7v on idle with multimètre on pim line when its idling and 2.66v ignition on engine off 

Shouldnt it be around 0.2v when idling ?

Can someone confirm this please.

If so, mean map sensor needs to be replaced?
