Ok, so on our way back from the park, I had Miranda rev my engine a little bit and I stood back by my exhaust. As I predicted, I'm shooting just a little black smoke out in higher rpms. What does this mean?

Mods are:
FPT28turbo
3'' turboback
HKS SSQV BOV
KN filter
Evo III o2 housing
NGK plugs

I guess I should add that my engine light was on, then turned off after Ichanged my brake pads. And also, upon startup, my car tends to rev itself to about 2500rpms. WTF is that?

enough said ;)

LOLOL.

Well you might have Idle surge.... Your fast idle valve could be getting to be junk... Mine was.

Black smoke could either be really rich or burning some oil... Check your compression.

black smoke = rich
blue smoke = burning oil

How would I be burning oil? I mean like what causes that, and what's the fix? As far as running rich...what exactly does that mean, do, and cause from doing it? Thanks alot btw.

Ouch you suprise me ricky...

BUrning oil = piston rings most likely, thats why someone mentioned do the compression. when you burn oil it means that every time there is ignition in the cilynder some oil burns.. logical? but since it is a turbo'd car you could also have bad seals in your turbo as well. another is valve seals could be hard and letting oil thru... those are pretty much the two situations where you could be burning oil, another one is a headgasket has cracked by the oil passage towards the cilynder but that would also cause your vacum/oil preassure to go up as well i beleive. I would inspect your oil and make sure it is clean.

Running rich, is exactly what it says, having a big fat wallet in your pocket!!! lmao no, you need to get safc and cut some fuel out so that you don't waste your gas. tuning will take care of this. But what you have to know when you rev your engine higher than 4000 or so you will be getting smoke out of it especially this time of the year!

I wouldn't worry about the smoke as black can be rich or lean.
rich - unburnt fuel
lean - burning the carbon off the tops of your pistons

Brake pads and cel are not related problems. The cel probly had something to do with your bov but I have no idea why it cleared itself.

Idle surge can be:
-Base Idle Set Screw (need new oring or new screw). Check by seeing if it started backing it out
-your vented bov can cause it as my hks and blitz did
-vaccum leaks
-bad ISC motor

A little bit of black smoke is normal for a modded DSM. How long does the idle stay at 2500 rpm? These cars are supposed to idle a bit higher when cold to help warm the engine and circulate the fluids.

It will do it for about a second. If you say one-onethousand, it'll be done. 92tsiawd82, did you vent to atmosphere with the HKS or did you recirculate it?

I did vent the bov when I had it. I sold it because of how shitty my idle was. Put your stocker on and see if it solves the problem. I hated how the damn bov gives you whiplash when getting off the gas.

I'd check the code stored.Certain codes will allow the CEL to turn off after so many ignition on/off cycles, but the code is still stored.It may also have freeze frame data stored, that could give you an idea of when(pre or post bov venting) the fault happened.

Venting a bov on a 2g does trigger a cel code. It has on ghettostyle's, remy, and Iceman's old 2g. There codes never cleared themself though.

FP28 with no bigger intercooler, fuel mods, or boost control ey?

....awesome

I would bet with that mod sig, he is not running rich.
fuel=power
flow w/o fuel=boom
remember that, you'll go far :).

I have a MBC. And I dont know how many times people have told me that I dont need to upgrade my fuel system. i was planning on doing a bigger fuel pump, but mostly everyone on here that i've talked to about this said that with my setup and that turbo i wouldnt need to upgrade anything fuel related.

Have you rewired the fuel pump? Not that you need MORE fuel at this point, but it's a good and cheap thing to do.
Venting will cause you to run rich when switching gears/at idle if I'm not mistaken.
You're running your exhaust without a cat., correct? That can cause the smoke to get a little black too.
