I went yesterday to the races... i did a 20 roll with a friend.... and now my car is like dying.... it seems its not boosting at all, and it pounds when i go at any RPM.... it feels like its miss firing like a MF... can anyone help me figure out wat it is... i havent drove the car in it started happening... it also feels like sometime it goes to limp mode the it starts pounding again...

 

Charge pipes blown off.

 

^^^ no its not that.... i checked the CP and they are fine... plus i dont hear any air leaking... its freaking weird!!!!

 

got a CEL?

Could be blown charge pipes or maybe a coil went out.

 

yeah but i havent taking it to the dealer cuz i dont wanna ruin my warranty... plus i have no 2nd ecu to put it back to stock...

i remember that someone told me that i had a miss fire on cylinder 4.... but that was a long time ago... about 2 months ago....
and now this happens.... could that be it?

 

plugs?

 

With the information you have given I would say bad plug or coil.

Try cleaning, regapping or changing plugs.

 

Did you ever replace them plugs like I told ya?

 

nop... i completely forgot!... i have a set of Zex one step colder spark plugs siting at my house... so if its the spark plugs i have them... if its the coils... where can i get them?

 

For the coils contact Tom at Crate Engine Depot he should have them for you cheaper then the dealer

 

dont put in colder plugs.

OEM are actually btr for the LNF

 

X2. It is not your plugs it is either a coil pack or a leak in the intake tract somewhere. What codes is it throwing P0101, P0300 P0304?

 

i got all this codes....
P0238
P0236
P0098
P0099
P2199
Wat does it mean????

 

Where are you? I'm the guy with the black Z who talked to you that night, you ran my boy's silver SS/SC. I could check the code with HPT and tell you whats up, maybe look the car over and see if I can figure something out for ya.

 

i just had a friend of mine check it... those are the codes that i got....
P0238
P0236
P0098
P0099
P2199

 

Those are boost pressure and IAT sensor codes... probably pegging the MAP or something.

 

P0236/238 Have to do with Turbocharger Boost Sensor 1's range being too high.
P0098/99 Have to do with your IAT sensor being too high.
P2199 has to do with IAT 1 and 2 not reading the same.

Not too sure but I would guess that the IAT is shot for some reason...

 

so how do i fixe those codes??? i fixed the runing rich problem... but now im not boosting at ALL.... and the turbo is purging.... a lot!

wats the IAT?

 

If you reset/clear the codes, either via a scanner or by unplugging the battery, does the car drive normal until you push it hard? Or does it fall into limp mode right away and the codes come back?

Assuming it does it right away, sounds like a bad MAF/MAP sensor or a shorted wire in the harness going to either of those. Most likely just a sensor.

 

DO NOT PUT THOSE IN.

OEM Iridiums ONLY!

 

IAT is Intake Air Temperature.

 

yeah when i clear the codes and turn the car on again, it seems the car goes into LIMP mode ASAP


why not?

 

lets just say there have been some problems with Zex plugs.

throw them out.

 

ooo....

is it possible that my turbo took a crap?

 

doubtful. Odds are you have a bad sensor somewhere if it's coming back on immediatly.
