Car idle really bad after cold air intake installed


i think it might be the MAF, its not upright but sitting sideways

Could it also be it has to learn that theres much more air coming in than before?

 

what brand of intake?

check and recheck your maf, that thing alone can cause many problems.

also make sure everything is nice and tight. hoses and pipes and such..

 

did you unplug the battery for 10 min?

i'll take a pic of my maf today and upload it. It looks something like the other picture of the guys cold air.

i heard that if the maf is not working correctly the check engine light will come on.

x2.

is this an si or a non-si?

 

haha mine is no where near there its def in wrong

 

it was just to show how the maf is faced...the picture was from the diy.

 

hmmm my maf is facing sideways and the plug is facing down... i honestly do not see that causing problems.

so the plug is facing towards the inject stamp on that picture?

this is where its supposed to be facing as shown in the directions...and i think it only fits one way?



check for any leaks, especially by the tb. is everything tighten down?

its more like as if that pipe is turned left so the plug is facing down

does it have to be level to receive an accurate reading?

 

Did you unplug your battery b4 you were installing it that could be the problem. and not to be a dick but in ur sig you have headerS. delete that "s" you have one.

 

Maybe positioned wrong but then again, I don't know how you could have done it wrong. Pretty straight forward when I did mine.

Oh, if you probably haven't already noticed: Poor acceleration at low rpm took some time getting used to. I don't know if the hesitation/bog has to do with the MAF or the design but it is definitely much more pronounced on the new SI*.

* okay, in all honesty, the bog is terrible

 

Honestly i dont want to f**k with the car now the CEL is on. I'm bringing it into the dealer really soon hopefully i didnt break the MAF them bitches are like 300$+


ill let you know what the problem was thanks for all the help

Yeah the cel will be on if u disconnect the MAF without disconnecting the Battery first...
Then the computer realizes that the Maf is connected and goes away.

 

I didn't unplug my battery before I installed my intake and I haven't had any problems.

Yeah i fixed my car no problems anymore and much more beefy with the cai in there.

THANKS FOR ALL THE HELP GUYS

 

A cold air intake, on a newer SI makes it slower off the line???

A CAI on a new SI decreases acceleration off the line?!?!

 

apparently. it might be right after cuz the ecu thinks ur still stock but after a while it starts to recognize that more air is comin in and it counters it by adding more fuel but idk. im not a cai fan anyways. i love the sri cuz its loud lol
