I didnt hear any noise that made me think its a chunked piston. But its forsure possible with it being cold and the OP's mod list. Hard to tell if its tuned. But yeah just pull the spark plug and see if the plugs damaged.
 
i translated in google. hes asking same questions, pretty much gets the same answer: to check for coils, wires, plugs.

Have you pulled your spark plugs yet? If not check them and take pictures.


You probably have one of the following problems.

1) I bet your car ate a spark plug.
2) You have a bad wire.
3) You Chipped a Piston.

-------------------------------------------------------------------------------------

Avez-vous tiré de votre bougies encore? Si ce n'est pas de les vérifier et de prendre des photos.


Vous avez probablement l'un des problèmes suivants.

1) Je parie que votre voiture a mangé une bougie d'allumage.
2) Vous avez un fil mauvais.
3) Vous ébréché un piston.
 
people in this thread make me LOL,

the Flashing light is not always a misfire its a "catalyst damaging condition" So yes it COULD be a misfire, there are other things that will cause the Flashing MIL.

i melted (not smashed) a plug and dont have any piston damage....imagine that

there is a very good chance his engine is fine.
 


For those who said i defenitly need heeders with 3.4" i readed on ZZP this following statement : "The 3.4 will give ~25 additional HP. Supporting mods that are required include colder Tstat, stage 1 throttle body, colder spark plugs, cold air intake, TB spacer, we recommend at minimum installing the Ubend delete, but the best exhaust mod is our downpipe." They never say we need headers but i understand it's better with headers. But i got better then the minimum they recommend. with my set up. I'll change all my spark plug soon n i'll take some pics. Cross fingers i didn't chip piston... Btw thanks for all your advice ! ;)
 
You dont really NEED headers but your car will be a lot safer.

If you like reliable, why not just wait longer and spend the extra money to make it reliable?
 
I want to change my headers but my wallet say no for now :(
Hopefully i'm not running my GTP right now. Tercel winter beater!!
 
ZZP has had that statement up there since they started their business what...over 5 years ago? I'm not saying you can't run a 3.4" with just a downpipe...I'm telling you it isn't safe unless you've got a way to scan for knock...and since headers are the price of a downpipe...they are always the best bet. You might take it as were bashing on you or your car...but were trying to help...many people here, including myself...have been through the whole chipped piston adventure...and it isn't fun. Trust me.
