Hi im literally getting 5-10 mpg
On my almost stock sr.

It has a bov
From
Prev owner on stock smic so i dont know if he wired
It wrong or whateber

But im running super rich.

At idle theres
Some random grey smoke that comss
Out sometimss that I see go to side of car.

My bumper iscovered
In black soot and when i go heavy throttle black smoke comes
Out.

My boost gauge shows im boosting fine to 7psi

But i have a big loss of power after4k rpm the engine takes
Forever to get
Past 6k and wont even make it
To 7k unless i floor it and wait a while.


If
Im parked for a few
Min u will see black soot on the floor out of my
Exhaust
Cuz its super
Rich.

Are these
Multiple problems or just a bad O ring or injector?

No loss of oil.
Maf seems clean.
Idk how to check 02
Idk if bov is recirculated but its purple and has a hole pointing down.

Its bugging me cuz i wanna pulll already!

Probably the electronic control valve in your blow off valve....

Now if i knew even the slightest bit about cars....i'm talking like if i knew how to change my oil (can someone pm me about this) I would say MAYBE try pulling the plugs and see what they look like. But thats a MAYBE.:confused:

Report back with your findings.

Yeah definitely check the plugs. They will tell you exactly what is going on.

Um yeah you obviously dont know anything about cars--> "electronic control valve in your blow off valve" WTF please dont give advice, lol

If he already knows its running rich then all the plugs will tell him is the same thing.


Check your injectors by unplugging them on at a time while the car is running to see if there is no change or a dramatic change when you unplug each one
You could have a stuck or leaking injector, or a leaky o-ring. you can also lift the fuel rail with everything hooked up then turn the key so that the fuel pump primes and see if there are leaks.

the smoke you see at idle could be your turbo oil seal going bad, you can pull the pipping off the turbo and look inside to see if there is excessive oil inside.

Check plugs to see if a specific cylinder is running rich.

If not, the fuel pressure may be way too high (faulty FPR????).

YOu need to be really careful.....if you are flooding the cylinders with fuel, you are thinning out your oil.

Change your oil ASAP, stop driving around like that!

At first I thought you were writing in some oddball iambic pentameter attempt..


Black bumper sooty?
Hard time revving above 4k?

Check the trouble codes, I bet it's in limp mode. CAS, CTS, MAF. Then check vacuum leaks.

Cliffs: Sounds like you need to take it to a shop near you. Check out Jordan Innovations or Steve Shadows.
