Just put in an intake/filter and the filter was too big so i bought a smaller k&n. the k&n is reallyyyyy smallll its almost funny but fits better so i put it on. Now my service engine soon light is on. This due to the really small size of the filter or is this a totally different issue?.....only 15,000 miles on my 03 coupe.

 

I think i remember reading it has something to do with the O2 sensor, but i don't think it needs to be serviced. Your car is just taking in more air than it normally does.

 

get it tested for the code @ autozone theyll do it for free and diagnose it for you.

 

I was thinking not enough air because the filter i just put in is so small. you think its getting more air?

 

The "service engine soon" light only reminds you to change your oil and take care of your maintenance. And if I remember the stock setting correctly, will come on about every 5k miles unless you've changed it to a smaller number yourself. If you change your oil yourself, you can get it reset by almost any mechanic or just wait and it'll reset itself eventually. Obviously, your intake filter has nothing to do with it.


The "check engine" light which would look very similar to the pics below, would be a reason to worry and run to check the code to see what's wrong, not the service engine light. If the check engine light (also known as the dreaded "CEL") comes on, then you would want to check the code to see what's wrong with your car. But if there's nothing noticeably wrong with your car, remember that false error codes are not uncommon.

 

The "service Engine Soon" light will come on for a number of different engine codes. There is no - recurring - "Service Engine Soon" condition that is related to time or distance. That light only comes up in response to an engine code. You need to have the car hooked to a scanner to determine the source of the problem.

 

+1 haha dofu noob

check out your airflow meter or the throttle butterfly valve thing

 

Thanks guys. hooked it up to a comp and said my ECU had a really small leak. hopfully thats all it was and wont be a problem...

 

? Mine just turned on, with no code???

Maybe I should check again...

 

i think you said you had testpipes rite? you might have a bad reader but you shold be throwing a lean code

 

Tuned... haven't been running lean for a while.

 

why you still have a cel then? want me to bring my reader next meet?

 

It's alright... I have access to one...

 

mine just came on today as well, is there any way to reset it manually?

 

Mine just came also. 13k No recent add ons. iwas planning to take it to Autozone. Seems to be running OK.
