So yesterday afternoon i was driving down to a buddies house for a party, which was about a 25 minute drive from where i am at, after and after being there a while we decide to head to some of the local beach-side bars in the area. I start my car as usual with my autostart (compustar) and when I get in I notice the check engine light is on. I lifted the hood and looked around (typical guy thing to do i guess) and saw nothing, and she was making no odd noises or acting weird in any way. I said "ah hell, ill worry about it tomorrow" and went about my business. I have no idea where to look and cant go down to a shop or anything to have them check it out, at least for a few more days. I have an after market BOV (had it for about 2 and a half months with no issues what-so-ever, a K&N drop-in, and the alarm with auto-start. Any ideas fropm you guys what i might be looking at? I'd appreciate any help i can get

Thanks

take it to auto zone get the code scanned then we can help you a bit better. Plus what year is your car?

 

03 and just turned 60k

 

like spaceball1 said go to autozone and report back with the code. you havent done any mods other than the bov in the last 2 1/2 months?

 

well, no i havent had any other mods in the time being (other than springs and some UK badging, hope she just isnt pissed at me for the badges haha). I did go to advance auto-parts yesterday, and sure enough as soon as the guy brings his cart out, the damn light went off and has been off since...who knows, i just have luck like no other...

 

FYI-make sure you put your gas cap on tight, that can make the MIL come on.

 

misfire code is my guess.

 

the codes should still be there even if the light isn't on anymore

 

Mine did that to when i was stock you can try doing a full throttle pul into redline a little bit most of the time the light will most likely come on again but it will only be a pending code so you will have to hurry and get the code asap. Thats how mine was when I was stock. You don't have an atmospheric bov do you?

 

if it was a misfire sorry.

 

Dreaded P0300 is my guess as well

 

so did you figure it out?

 

i dunno, just said f*** it for the time being, i have to head down and get an alignment this week (thanks mom), so ill talk to them about it when i go down


thanks for the input tho guys

 

just got the p0300 code I have intake exhaust and a MBC. I have had this stuff on the whole time. My car has 13k on it. What causes the SES light to come on? Do I need to change plugs or something. Light turned off when I put gas in the car that same day it came on.
