Fouling all 4 plugs

[Decker0004]

Ok I am having a problem with my car fouling all 4 plugs in a matter of about three miles. I am at a loss. the car set for about three months and I started it ran it for about 15 to 20 miles and fouled out the plugs. Now if I put in a new set it is fouling them out within 3 miles. I have replaced three sets this week. They are dry fouled with heavy carbon. I realize this means it is running rich but I can't understand why it is fouling all four. Thank you for your help.

Small mod list:

act 2100
190 fuel pump
boost controller
down pipe and test pipe

i had the same problem with those exact same mods, drove next door to the gas station and back (2/10th of a mile) and fouled them up... then hooked up an safc and pocketlogger even with my stock injectors and i was running really rich, might want to check that out if one of your buddys has a logger

you are using ngk spark plugs right?

 

[BoostActionBob]

i think the bpr6es is what you should be using with your slight mods list there.

fast what did you do to fix the problem? Yes I am running ngk.

Can can purchase an SAFC and turn down your injector percentage so they won't dump as much fuel or you could simply add more boost as odd as it sounds. What psi are you running on your 14b? I would recommend getting an SAFC and pocketlogger then you can tune how much fuel your car uses.

Not a bad idea to make sure your car is making 14 volts. I had the same problem and it turned out my crank pulley was seperated which caused the alternator to underdrive and only make 12.5volts. Just idea.

Even at 12.5V it will provide the coil with enough juice to fire off each cylinder. Until you get down to about 10.3 volts. I am still going to say it's a tuning issue and you need to get some fuel controll or add most air to compensate.

would a maf translator and a 3" maf do the trick

Would help tuning wise. But you should really try and pinpoint your problem first. Check your fuel pressure or find a regulator you know works.

I have a fuel pressure gauge on the way as well as a pocketlogger.
