maybe if i have some time tomorrow, ill check around the intake. make sure its all on tight.

 

It's worth it. The engine book alone is nearly 3" thick.

 

I would take a stab at an intake pipe leak, assuming that is the code being thrown.

As for the service manuals, they give a great description of the DTC, and the conditions that are required to set it, however, in this case, they don't give the requirements as accurately as logging in HPTuners and witnessing the code being thrown. The service manual states the code will be thrown when "certain fueling requirements have been exceeded". Our experience has shown it throws the code at anything above a 20% trim adjustment, on either side of the tuned MAF or SD calcs.

 

Did u put gas in your car sometime before it came on...maybe the gas cap isint tight.

 

i already checked the gas cap. it felt tight, but i unscrewed it and put it back on anyway and still have a light.

 

Well, if the gas cap was the problem, the light doesn't go away after you put it back on. You STILL have to go get it reset. Would you just go to the dealer already! Geez.

 

Mine has had a little sputter when I start it up for a while now and the cel light came on one day last week, took it straight to the dealer they read the code said it was a misfire. The guy deleted the code and said if it comes on again bring it back no prob. since.

 

well last time i had a gascap problem the DIC gave me an error, not the light. it said check gas cap. and i wasnt gonna take my car to the dealer on christmas eve lol.

 

i went over my intake today. some stuff was loose, tightened it up. unhooked the sensor and plugged it back in. still CEL though.

called the dealership and im taking it in tomorrow. do u think they will give me **** for my intake? it is the GMPP intake, though i installed it myself. should i lie and say some other dealer installed it?

 

There should be no problem with your intake -- it's a GM part and the warranty is not affected. Just have your receipt with you to prove you bought it through a GM dealer.

Let us know the outcome.

 

Okay, as I have said now many times, correcting a problem does not make the CEL go away. The error code is stored and needs to be physically erased from the memory. You might be able to reset the CEL by disconnecting the battery, but the code is still in the computer. So you still have to get it cleared.

Quit living in paranoia! Don't make up stories about who installed your parts. Just take it in, say "I have a CEL", then shut the **** up! Don't say I bought here from so and so, I installed it myself, somebody else installed it, just STFU! The dealer will read and clear the code, tell you what it was, maybe make some recommendations, and then you say "thank you", STFU again, and then go home. PROBLEM SOLVED!!!

 

Is this how all the moderators act over here? I thought mods were suppose to set examples for everyone not act like a bunch of teenagers.

 

your wrong. correcting the problem will make the CEL go away. sometimes its as easy as letting the computer learn what u have done to the car. and for you to say that jus clearing it will make it go away then your an idiot. and i cant believe your a moderator. do you even have any mechanical know how? what about a lean code? that ive cleared 11ty billion times since my stage 2 flash. which has now gone away and displays no codes and no CEL. and i did nothing but let my computer learn my intake over 500+ miles..you dont jus reset the CEL by disconecting the battery you reset the whole computer. and untill the problem is fixed or the computer see no problem thats what the CEL is for. IMO follow your own advise.

 

No wonder everone calls this place the shortbuss!!!

 

I know my CEL goes off and on by itself when I go lean sometimes. Always seems to fix itself.

 

wow, bad form mods, bad form.

 

what exactly is a "lean" code? like what does lean mean?

 

Not enough fuel. (the proper air/ fuel ratio is off)

 

ohhh i see. thanx! well ill def post the outcome tomorrow. hopefully they dont have to keep my car until thursday. and hopefully nothing serious. i got alot of stuff i need to order.

 

No, it doesn't. It means the fuel trim correction has gone outside it's boundaries. Usually happens from too many mods and not enough tuning. The computer's ability to learn within certain preprogrammed vaules has been exceeded. The car does not run lean however.

 

The computer is sensing a lean condition. Of course it is not running out of fuel. It is a result of more air coming in without adjusting the fuel demand for it.

 

There is no lean condition, the DTC is for the Fuel Trim System being exceeded. When the code throws, the O2 is still sweeping as it would be any other time.

 

Alright everybody, listen up. If you want to jump on my ass because I'm a mod and I used the **** word, then you go right ahead. Paint the bullseye on the easy target. But here's the facts.

The poster has not simply brought his car in to have the code scanned. He is afraid he will somehow be yelled at by his dealer, told his warranty his now void, and sent home. He has spent more time worrying about the problem and posting about a CEL that by now he could have simply fixed it like he was advised to do throughout this entire thread.

He started talking about unnecssarily lying about it to the dealer. Once I read that, yes, I told him to quit freaking out about and just get it fixed. People get themselves in more trouble with their mouths by saying stuff that just doesn't need to be said. Yet people still open the mouths anyway, and just like the posts in this thread, every now and then, you need to tell them to SHUT THE **** UP for their own good. You want to say something on here, on the internet, that is complete stupid, go ahead, thats what the internet is for. If you plan to do it in real life in a place where it's going to cause you trouble, think first.

And since this thread is no longer about helping the original poster, who is obviously not taking the advice given to him that he sought, and is now completely off topic, I'm closing it.

Think I'm being condesending? Think I'm abusing authority? Think I'm trying to avoid your rebuttals? I'm not, plain and simple. I'm doing my job.
