Sorry for my ignorance but here i go.
I have the SES light On how can i know if i have p0300 code?
The dealer diagnosis will throw this code?
Can cause damage to my engine?
My mods:

Jam stage ii 2.0 short block
gsc s2 cams
TBE
20 g turbo

06 EVO IX.

 

Newer ecuflash can read codes. See what code it is, or buy a Creader off ebay for $30 bucks and plug it in and see (if you're not too savvy with tech).

 

Ok i will downaload newer version of ecuflash.
Regards.

you can use the tactrix cable to turn the code off too.

 

There is no problem just to turn the code OFF.
This code will not damage my engine?

 

How can i get the codes ?
just open the rom and go to OBDII?? and check the codes in blue?

Im right or not

Regards

 

 

Go into the Periphery bits

Change FCA, bit 4, from 1 to 0

Ahhhh no more P0300

 

Finally p0505 code " Idle contro system malfunction"
Something to worry about it??

 

Sounds like you IAC (idle air control valve) may have gone bad or is disconnected.

Pull the Throttle body off and remove the IAC and inspect the corners of the valve...if they are worn...replace it. Might help to clean it too.

 

To display your codes....click the "display DTC" button on EcuFlash.

 

Ok thanks a lot i will try to clean up.
But is not a big issue this code?

 

You may have issues with stalling, and/or bad idle.

 

Ok thanks again for your help and patience.
