Emissions system
 

So this morning on my way to class I realized my check engine light was on an I looked on my navi screen an it said somthing about my emissions system does anyone know what this might be cause I have noo clue.

might help if you gave us the code it threw at you.

Darn let me check

btw, to clear the codes. here is what you do.

you'll need to evoke the diagnostic screen first, get in your car, turn the nav on, and hold down the "GUIDE", "MENU", and "CANCEL" buttons for about 5 seconds. The factory calibration screen will come up.

then click on XM module, and you'll see the option to erase those messages.

The code is p1078

P1078 Intake Mainfold Runner Control (IMRC) System Malfunction (High rpm)...this code make reference to low idle engine,maybe the throttle body is dirty , air filter clogged, vacumm leak , pcv valve clogged, check for those.

press odometer reset/adjustment and hold, hold in and turn key to run position. Keep holding in the reset shaft in for about 30 seconds. release button. turn key off. restart car. service light should go off in about 5 seconds.

then do the nav screen reset like i said above.

I tried it but im not sure if I did it right cause my car doesnt have the odometer shaft I have to press the button on my steering wheel is that the same thing?

Is this somthing major I have to worry about though?

^yeah i would say any CEL is something to worry about.

try clearing the code with the nav screen method i outlined and see if it goes away.

p1078

you know you dont have to start new threads over this?
the Houston crew can haaalp you without you starting new threads!!!

we're going to dennis' this weekend.
we can take a look at your intake manifold and clean it.
if needs to be

Did you mean data reset or somthing like that cause thats all I saw when I did the navi thing

Alright sounds good!
