Hey Guys,

I just got my GM Stage 2 Installed on my 2007 Cobalt ss/sc and everything was Fine for about 8-10 Days and then all of a sudden my Check Engine Light comes on? Has anyone else Experienced a similar problem? Thanks for your Help!

it could seriously be any of 150+ codes. take it to the dealer. it's under warranty

Sully20

Thanks for all of your Replies....As I said, I will be taking it back to the Dealer sometime this week. Hey Punksk8ter62 what do you mean when you say "Got returned and now no more problems?"

Re-Tuned. Basically loading the flash to the ecu again.

retuned,its a process where somebody rewrites your cars ecu

Sully20

Oh...I'm Sorry, I thought your Post said Returned Not Re-Tuned, My Bad, I Understand, Maybe I'll mension that to the Dealership when I call Tomorrow. It's Really Frustrating Though, I'm FN Pissed! I just spent like $900.00 on the Damn GMS2 and Now the Stupid CEL comes on like 2 Weeks Later?! I'm starting to wonder if this is a some what common thing? Thanks

Cel codes are common. the amount of time youve spent on the forum asking questions about a cel light you could have drove to auto zone or advance auto and have them tell you what it is

Since its a guessing game i say the codes a p0171 and possibly a misfire code like say p0300......... Since he does have the airbox mod..

Sully20

Hey Chevycobaltss3, Your Cobalt has to be Sick! I see your a HUGE Fan of Hahn, Just Wondering how much HP you Puttin Out?

Also, I have heard quite a Bit of this "Misfire Code" Whats the Deal with that? So my one of my Cylinders are mis-fireing? Thanks

Well LSJS are prone to the misfire code . But in most cases the p0300 is caused from the tune like injector scaling , offsets and ect. But in your case i feel it owuld be either your spark plugs or your aibox mod. Making it run to lean or to rich!!!!! My car is slow man hahahahaha. The hahn stuff is on here from previous owner, i just fine detailed everything like changing compressor wheels, builing the engine and tranny, and ect..... and retuning it!!!!

Sully20

Yeah, I just got my CEL Read and Here's the Code: P0496 Which I was told is a Evap Perged when should Not have, Whatever that Means? The Mechanic Basically said it has to do with Air Mixing in with the Gas when I Fuel Up at the Gas Station(s), He told me to stop trying to put more gas in the tank when it stops initially the first time. I have had the Air Box MOD on for quite a long time and it Never threw a Code, So I really didnt think that it was the Air Box MOD, But has anyone heard of this CODE? Thanks

p0496 is a purge Solonoid code on the engine (Replace the solonoid) It is like 30$

Sully20

So, your telling me that I should Replace the Solonoid? Cause I work for a Ford dealership and our Service Manager said its No Big Deal, to "Not Worry about it, Unless the Check Engine Light comes on agian". He basically just Cleared the Code/CEL and said its Nothing. I swear our Service Dept Sucks, Thats Half the Reason why I drive a Chevy!

Dude i am a certified tech (well was like 2 years ago lol ) had all m ase' except for manual trannys. Replace the solonoid...... Your service guys a idiot.. If you over fill the tank itll first hit the purge valve on the canister so therefore ruin the canister. and ect. purge solonoids go out often. replace it!!!

Sully20

Thanks Bro....You were Right, After My Jerkoff Service Manager Cleared the CEL the other day, Guess what Happened?? The SOB came right back on Again like 2 days after he cleared it! I called my local Chevy Dealership(Who have been Great by the way) and they had me bring my Car in Yesterday and they Replaced the Purge Valve? I'm pretty sure thats what it was called and they did it for FREE I might Add! Thanks for Everyones Help!

yep just replace that little sensor and it'll go away. i had the same problem about a month after i bought my car. it was right around $50 from the GM dealer and took maybe 5 minutes tops to change it out. very very simple fix. nothing at all to be worried about.

Sully20

Hey Nick,

I noticed that your Cobalt SS has those HID Front Lights, They look pretty sick...How much did those run ya? Cause I would like to get those for my Balt.
Also, Not to Hijack my own thread, Lol, But How were you able to get a pic of your Ride on your Signiture? I tried and it wouldn't let me for some reason? Thanks

i bought morimoto h1 mini projectors from buyhids.com and retrofitted them myself. took the lenses off painted the headlight housings black and customized the headlights as needed to get the projectors to fit.

here's kinda a crappy pic of them.

Sully20

Those HID's are pretty Bad Ass, So what would something like that Run Me and do you always have to screw around with them to try and make them Fit? Thanks
