allright guys, i'm new here and bought a used turbo s2k 3 weeks ago. This s2k was turbo a long time ago, if somebody remebers about Flexer black s2k well its his old one. i'm here because i need help, my car is at a tunner shop right now(and coasting me big ass bucks to find the problem). The car haves a rough idle and seems to miss firer alot.the first and fourth cylinder are good but the sedonce and third are of about 20-30degres.

what we checked and done
-changed the sparks plugs
-tryed another coil pack
-good compression 210 on each
-checked the injectors
-tryed another AEM
-the first and fourth cylindre are steady but the seconde and third are not.

heres a bit of the setup
Gt30-70
AEM EMS 1052
2mm Cosmetic Gasket
255 Walbro Fuel Pump
750 cc RC 12ohm injectors
Lovefab V1 Manifold

Lovefab 3" Mid pipe
Modifry AEM Stock Temp sensor Controller
RFL Blow off Valve end more.

some update down the page

 

Can you get in touch with the guy who sold it to you? or who originally tuned it? Check your injectors. here on forums they tell us they might get stuck open (or closed). What boost? What about your MAP sensor? what kind?

so what can the problem be to make the seconde and the third cylindre not steady?

 

check your EMS initial settings maybe your vehicle parameter/s are incorrect, check your throttle signal etc...

 

clarify what's "not steady"? do you have a CEL?

 

Why not post in the FI forum?

 

RC injectors may get stuck closed every once in a great while under big boost. But that's obviously not your case.


Did you open the engine?

 

ok, i stole my bro's injectors witch were the same one as mine. the car runns GREAT!! but, what do i do with my injectors witch got stuck, clean them rebuilt them buy some other ones?

 

You'll get more and better responses if you move this thread to the Forced Induction forum.
