I have B18b tuned and was running well all the time, but last night there was lots of black somke coming out of the exhaust and the vacuum reading was @ 16 ( it was always @ 21)...... Any idea?
Could it be the gas filter? Spark plugs? Injectors??
your help is highly appreciated

Setup:
B18B
T3/T4 .57 trim
DSM 450s

Black smoke is overfuelling

 

yep running rich, any big change in outside temp in the last couple of days?

 

Black = fuel
white = coolant
blue = oil

 

if you have black smoke you should be smelling strong fuel odors,

do you have a wideband in the car?

do you have a fuel pressure regulator?

what are you tuned on?
