i noticed two days ago my check engine light came yet i feel no difference. wut could it be? i asked onstar like 8 times and they couldnt find anything, also took it to autozone and couldnt pick up anything either yet the dam light is still on. any suggestions before i take it to da stealership?

 

sometimes they'll come on if the gas cap isn't sealed properly.

 

get the code scanned, that's it. no one can help you without the code.

 

get a reader.......my friend had the same thing happen........turned out his stage 2 tune wasnt tunned right and he was running lean and there was no noticeable difference in his car........o ya and tighten all your caps (gas, oil, radiator, etc.) just to make sure

 

hit the onstar button and have them tell you what it is

 

i already hit the onstar button n no codes came up same thing with the scanner no codes came up.

 

if the gas cap is off it will tell you, ive been going throught that the past two weeks and the cap is tight

 

I had that message for the first time the other day. Hasn't come back yet. I figure it was cold weather problem.

 

wait, are you sure its not the low tire pressure light?

 

Check your fuses

 

if the CEL is on and no codes, that sounds like wacky problem. wacky like ECM or cluster malfunction

if the problem is in the cluster and onstar and autozone don't scan it you won't know

 

Look i work at a chevy dealer. your car is most certainly under warranty, take it to the dealer. i woudl not recommend anyone to goto autozone, advanced ect for diag. they are a parts store, not a service center. we get people with problems , that went to autozone .autozone ect clears the code , and when they come into the dealer it makes it hard for us ot diag the problem. on another note to who ever had problem wiht the gas cap. there is no code for the gas cap its evap large or small leak. a gas cap is just a quick thing to check if you get an evap problem leak code. also make sure it is the cel. if its the tire light and somethign for everyone to keep in mind, the weather is changing, getting colder, and on a real cool mornign the air pressure in yor tires may go below 30 and set the light. so to eliminate the inconvience of the light I recomend running your tires @ 32psi
