black spray from exhuast? (rb25det start up)

[rb24t]

ok guys, when i start my car (rb25det series 2) it will shoot black liquid from the exhuast pipe and if i rev it a little it will shoot it about six feet behind the car. it idles like crap and will die sometimes when pushing the clutch in until it gets warm or drivin a bit. today i put a new q45 maf on and a new 02 sensor and started it up and it idled great, a little high 1300 but perfect no sputtering or poping it really sounded good, but it still shot out the black liquid until it got warm and then stopped. i no i probly need a nismo afpr but i cant seem to figure out what would cuase this to happen until the car warms up?

my set up is this

i have only put aboout 200 miles on it since it was tuned and it did this ever since?

is it water and soot or is it oil?

[Largekid]

looks like my car....its carbon buildup and moisture in the exhaust. Its caused from running retarded rich

[Joe]

normal.

[rb24t]

its not oil or coolant its more like just plain water mixed with black chualy ****. and it only does it until it warms up?

[Carl H]

normal, my driveway has a spot on it permenantly from where i park my car lol.

[Joe]

its just carbon from the exhaust being knocked loose from the heat/expansion/water being produced from cold combustion.

dont worry.

DIRTY INGECTORS WILL MAKE YOUR GAS BURN LESS AND IT WILL CAUSE THIS. PUT A INJECTOR CLEANER WITH A FULL TANK OF GAS AND IT SHULD CLEAN UP. ABOTH $3.

[rb24t]

im running brand new deatchwerks 650cc injectors and they only have about 400 miles on them

[USMCgetsome]

check your fuel injector orings!!!!! i bet there not sealed properly. Pull the rail and inspect them.

[Joe]

wtf are you guys talking about

this is normal

why do you think an improperly sealed injector will cause this?

[lazyboi444]

Its normal guys lol. My KA does it. Just spits all over my garage door. Think its like water + carbon build up or Fuel and Carbon build up. Either way nothing harmful. Suggest cleaning it up before it settles though lol.

[raremotive]

A combination of condensation and carbon that lays throughout your entire exhaust system.

In other words.

Normal.

Normal. I started the car with the garage door closed once. Needless to say, that was the last time I made that mistake.
