so my car is stock. ive had it since November and ive had it in service 4 times now for various things. needless to say im pissed. but im even more pissed because today i drove all the way from my home in NJ to my school in PA and now...when i actually have **** to do my check engine light is on. This happened once before and they told me to use premium fuel which i already did. i dont use anything but premium and the light is on again but the car runs fine. anyone else getting a light with no symptoms?

 

what code u getting? u think u have it bad, i had a defective sunroof and motor in my car, was in the shop for about 2 months total.

 

i dont know the exact code from the first time andi cant get the car in until the end of this week. **** blows bout the ur ride man...some bullshit

 

i had to have my MAP sensor replaced and bought my car same time u did. now i have a check engine light and the code is for LOW VOLTAGE FOR MAP SENSOR..... i dont know what is going on..

any help would be nice

 

if there is an autozone around, they'll pull the code for free, shouldn't take more than about 3 minutes. at least that could give us some idea.

 

were you no-lift shifting? You might have misfired

 

sounds like a lemon in the works

and no stock the only code i ever thrown was maf sensor

 

it could also be something stupid like u need to take ur gas cap off on put it back on. did it show up after u filled up gas? cause the code doesnt usually go away unless u erase it from my experience. get a code tool so u can check and erase ur own codes in the future. its worth not having to do to dealer and paying for something that takes 2 minutes

 

I get a minor misfire code all the time. I've had it to the dealer twice and they don't know what to do. It never does it when it's there of course. The cel does eventually go off by itself. My just came on again about a week ago and its already reset itself and come back on again. lol. I don't know if I need to be worried. It runs great. No other problems at all. I run 91 octane gas because its the best they got here in Utah. Maybe 93 would be better. Who knows.

 

i did the gas cap trick because i know that'll throw a code...but i have an auto zone down the road ill hit that up today...good tip. as for the lemon possibility i was thinking the same thing. i run 93 here in jersey

 

prob just your map sensor on your intake i have the same thing.... i just ignore it i don't feel like untuning my car going to the shop getting the sensor replaced and getting my tune out back on lol..... btw you should go to the best buy meet on tue nights (when it is nice like 200 cars) and there are 4 turbo cobalts that go.... right now i am the only one that is tuned.... but i think one of us is getting trifecta..... (trifecta vs ttp race in the works )

 

why do people get so worked up about a cel? like it's the end of the world, or their car is going to blow up

if the car drives fine, chances are it's nothing to worry about. get the code scanned.

 

Me too on the sunroof waited two months and it still leaks air at highway speeds. To the Op what code is it? If the told you to run premium fuel maybe it is a lean or misfire code either way they should fix whatever it is.

 

I race mine on the weekends, and honestly, it wasnt a fun weekend uless the light comes on... Im not sure what code it throws, but generally after a refill of my tank and about 20 miles it shuts off again.

Edit: It runs fine for me before during and after the light comes on.

 

im actually at school in PA right now... i should be back in june but ive seen some pics...ill come when i get back.

 

is ur sunroof totally flush with the roof, mine wasnt and they tried to fix it, finally i took it in and said either they fix it so its totally flush or get me a new car. they had to order in some part, but it sits totally flush now and only starts to whistle at about 120 mph, so im happy with that. make em fix it right, u paid for a fully working car, not a half working car. tell them that to.

 

fwit, the dealer service manual says to adjust the sunroof so the rear is just slightly higher than the front.

 

mine was more than slightly higher. it was like half an inch higher

and thats stupid, i dont agree with the manual, look at every car with a sunroof, they are all flush.

 

noise at 120 mph. doesn't sound right. i had absolutely no noise when i got into the 130 club. sounds like something is still wrong with your sunroof.

 

well it all seems fine, ill leave it how it is, im tired of taking it back to the shop. maybe needs a little adjusting. whatever i dont go that fast ever anyway. well almost never. lol

 

Misfire Code FTW!

I took it into the dealer and waitied 2 hours for them to tell me the CEL was nothing. OOOOOO man I was pissed lol.

 

I have a friend who hasn't even had the car a month/1k miles, and he's on his third map sensor.

I don't know which of the two the continue to replace, but it's starting to get pretty pathetic.

my 08ss luckily has only thrown codes that were my fault.

 

i havent thrown a code yet im on 5000+ km

 

If you bought the car new, then you have onstar for a year right? wtf dont you get onstar to run a diagnostic code on it? They will tell you EXACTLY what the code is. Hell you can even speak to a tech and they "usually" can tell you how to fix it.

As far as gas cap code goes. You have to let it warm COMPLETELY up, then let it cool COMPLETELY down, 7 times, then it will disappear. I've had 2 codes. Gas cap, and Cam shaft sensor came unplugged.
