After installing my HAHN intake my car seems to be sitting around 900-950(normally right at or a little ovee 1k) rpms and bogs out pretty low when i first start it up. is there anything i can do to stop this besides a tune? gap my plugs a little more?

 

tune is about it i think man. besides, the computer, without a tune, is supposed to compensate for things like that.

 

hm. ok. where at in HB do you live? I grew up behind the philly cheese steak place off of beach. not to change the subject....

 

I know this is probably the first thing you checked, but did you make sure you did not install the MAF backwards? That would cause boging and idle issues. I have a Dejon SRI with an AEM filter and I have no boging or idle issues in fact I think it pulls a little harder now.

 

Haha, Edwards and Slater, over by Hope View Elementry. My home station is at Fort Bragg, so i'll be part of the NC crew when i get re-deployed to the States.

I didn't even think of that, good call.

 

yeah i was occ about installing that backwards and triple checked, but maybe i somehow ended up installing it backwards.... but wouldnt that have thrown a cel? im already 500 miles into this mod? now it only bogs down when i first start it in the morning and when its wamed up it idles fine....

 

^that may have something to do with the larger amount of cold air combined with the cold engine. I know the SC'd cars have problems compensating for the change in cold air density. that might be your issue, but, i am not an expert.

Right on, yeah i miss ol' southern cal. sure wish i was chompin down on a double double right about now.... or maybe some tacos from jack in the box....... im going to re install my intake this weekend i think. i need to fit my elbo back onto my turbo caus ei guess it worked itself a little loose and i can see metal. and ill also check my maf. it sucks though hahn didnt send me new maf hex screws in my order so i had to re use my old ones and make new threads, and a day later they arived fedex with a sorry for forgetting note lol.

 

haha, that sucks, but hey, mistakes happen.

Yeah In-n-Out is amazing, and nobody understands how it can be so good until they try it.

 

for real. people think your a tard when explaining the greatness of in n out.

 

I just installed my Hahn intake yesterday and im pretty sure they make the bolt holes on the MAF in a way so you can't put it in backwards. I almost did it but the holes didnt line up.

I don't have any boggin issues and my idle is normal and i haven't tuned it yet.

 

oh trust me you can put it upside down. Been there done that and scratched my head for about 10 minutes wondering what the hell I did. lol then I realized it was upside down

 

If it can be installed upside down, than someone please show me a pic of how it is supposed to be installed. Either way, mine idles rough at start up, but I believe the computer is compensating for the extra air flow and reworking itself. Either way, I let my car run for about 10 minutes before I drive it and havent had a single issue yet.

 

I think everybody's SS/TC idles rough at cold start up. Mine does & it's practically stock!

The RPM's flucuate up & down a few times.... Is this what your experiencing?

 

^ yes true. When I put the sensor in upside down my car wouldn't even start so I don't think that's you problem

 

Lmao.

 

When the car starts up in the morning it goes into cat warm up mode and injects fuel on the compression stroke as well so it runs kindy funny to begin with so adding the intake with will have some effect on A/F ratio will causeing it to become either a little leaner or richer than stock. Once you get it tuned the problem will probably go away. How does it run once it is warmed up? Yes, you would have thrown a CEL before the 500 mi mark. I though you just installed the intake like say 50 mi ago.

 

yeah i have a rough idle sometimes and im stock

 

in cold weather mine bogs and jerks when i start driving if i dont let it warm up for a minute or 2. im totally stock for the moment

 

I noticed with my Hahn intake the throttle hangs a lil n thakes a bit longer to drop to idle rpm rather then drop fairly quick like it did when stock

I dont got and booging issues or anything of that kind

 

If you put that MAF in backwards your car stalls in seconds, trust me, ive done it >.>

 

if you think its in backwards take it out im pretty sure it has a arrow on it telling you the direction the air flows across it not supper sure but i cant take mine ot to tell you sorry, i would just it had a leaking seal on my custom intake so i sealed it in with sensor safe rtv haha ghetto i know
