Hey Guys,

So I installed my Hahn intake, Charge Pipes, and Intercooler today... took me a little white but all is well now! Except the CEL. As soon as I started the car up and let it run for a bit... I got a check engine light. Should I be worried about this? Will it go away on its own?

Also at one point (only happened once) I drove the car for a bit, all was well. Got back home, I was letting it cool off and then all of a sudden the idle began to flutter. It would go from 1000rpm to 500rpm and then back up and down, etc. The boost gauge was going crazy too, from like 20 vac to 5 lbs every time the idle jumped. So I turned off the car, waited a min, started back up and its fine and has been ever since then.

Any ideas/help for me?

Thanks

How's the breather hose on the intake?

CobaltSS_25

Its attached and looks fine... I tried to get it to pull off and it wont come off so i think it is ok.

IsItFast?

whats the code?

CobaltSS_25

How do you check the code? I don't have a reader. Any other way? Also my car runs around 92-94 at idle. Nornal?

Sorry for all the questions, I just want to make sure its all ok haha

Go to Autozone, they can read the codes for free for you. I bet you the code is either lean at idle speeds or MAF.

92-94 at idle? Is that mph? Wow!

Seriously, what do you mean by 92-94?

X2. Probably a MAF code or map sensor code if the map got messed up during the cold pipe install.

my only guess would be that the computer is playing its stubborn game of not wanting to learn all the new mods, see, i got all the hahn parts, and pushin more boost, and that causes my CEL to come on all the time for no reason at all, pushes it into limp mode until i turn the car off, then i gotta disconnect the battery cable for a minute, plug it back in then its fine.... the stock sensors pretty much can learn to kiss my A** cuz lol i aint even tuned yet and i'm always havin to deal with the stubborn computer...

i have all hahn stuff, and knock on wood,

have not had any cels for thousands of miles

Those CEL are coming on for a reason.
Your car is going into limp home mode for a reason. Keep driving it around like that for a while and see what happens. You need to get a proper tune. Maybe nothing will happen but if it is anything but a underboost or overboost code it is going to do some damage over time.

Haha sorry what i should of said was it is running a bit warmer at idle then normal... is that supposed to happen with a charge piping/intercooler install?

And I just got a code reader, i will read the code and post it on here and see if you guys can help. I will also re-check all my connections.

Thanks Guys!

Telling us what code or codes will definately help us diagnose the problem.

K so I ran the code. Its P0103. I also got a superchips tune. How can I fix this code from coming up again. Thanks guys.

Terminator2

P0103 MAF circuit high input.
First try just disconnecting the negative battery terminal. If the code comes back it is the intake most likely causing it. It usually means that there is a leak near the the MAF of the MAF could have been damaged possibly. You could also have a big CP leak somewhere check all your couplers and clamps.

CobaltSS_25

Thanks, will do! I will let you guys know how it goes.

Soo I tightened the sensor on the intake and cleared the code... all the fittings are tight. So far it hasnt come back... lets hope it doesnt haha

make sure its plugged in, i forgot to plug mine in once and got that code. lol

badbaltguy

ok, so for my CEL that every once in a while comes up, it is not an engine threatening deal, its just an oh **** what do i do with all this air kinda deal.... how it happens, i boost slow, like on the highway at 70 mph in 5th gear if i just lay into it, and boost builds, takes longer to boost, and it drives the sensor nuts and then shuts itself down, no problem, shut the car off, and BAM,,, problem solved. boosts fine again, no lights. now do you get it? i think i would be able to tell if i was F****** up my engine. i'm not a mechanic, or an all around vehicle genius, but i do know what goes on inside there, and what not to do, and what to do if something goes wrong. so please stop placing me as a noob lol.

Terminator2

Get a proper tune and those codes will go away. Those are underboost modes more than likely they dont cause any real damage but your car will go into limp mode and who wants to disconnect their battery everyday. Your max airload torque and desired airload tables needs work that will fix your issue.
