hey guys i wanna start off by saying im a newbie but ive been looking on this forum alot for help and what not but my issue is that i installed my stillen gen 3 intake in today and i have a check engine light on and my car boggs down and has a rough idle, i checked the code and its a mass air flow code. has this happen to anybody else and how do i get rid out thisa problem or is it just better to go back to the stock air box. please really need help guys. thanks ohh yea and my check engine light flashes .

 

If you didn't already do it, reset your ecu. Make sure everything is tight and not half assed installed

 

I did the same thing when i got my intakes....i was so anxious to get the car started with the intakes on, i forgot to plug in one of my MAF sensors. Threw a code, my friend cleared it and it was fine. Sooo, with the being said, check to make sure both your maf sensors are properly plugged in.The code can be cleared at any autozone.

 

i checked to make sure everythign was tight but i didnt reset the ecu. how do i do that? and its deffenitly not all rigged up i didnt it at my friends shop (its nice to have all the tools lol)

 

Well you can either do the rest routine or you can just disconnect the battery for like 15 mins.

 

ECU reset

Also, the car bogging down sounds more like a vacuum issue to me. The car will run with an MAF code, it just wont run normal during regular driving. Being that we have two maf sensors the car can run with one maf reading, it just wont run under load. My car ran fine with the MAF unplugged. I wouldnt have known if it wasnt for the code. Rough idle and bogging sounds like a vacuum leak somewhere. Ide double check all hoses in the area.

 

Thanks for the help guys ill give it another shot tommorow and ill reply back hopefully with better news

 

Any news?

 

No issues with mine. I would check the install again and disconnect and reconnect the air sensors.

 

maf sensors - unplug em and reconnect carefully. make sure you didnt let any dirt or crap get in them. as far the battery reset, the g35 had to be left disconnect overnight, not 15 mins...

 

I agree its prob mis-plugged maf sensors

 

i guess no issues if the guy hasnt posted in awhile....lol

 

Check for leaks.

 

g37 requires 15 minutes only
