Hey guys, so i put my cold air intake on last week and now the car is def. running rich. I can smell it sometimes but my main point of concern is the check engine light that came on yesterday. Some guy at jiffy lube checked the code n said that cleaning the injectors might fix it but i know its bc of the intake. Im wondering how safe it is to run the car like this. I have 90k miles and a 2.5 in catback with no supporting tune. I havent gone into boost at all really since the the comp threw up the code. Can i get a supporting tune w/o the cobb access port? Will running rich harm the motor? Should i remove the intake or do i have at least a month to get a tune? Any info will be a great help! Thanks
If so if it were me, I'd never want to see the intake again in my life. Either throw it away or since it's two pieces see if you can use either piece as a flower pot and throw away the other piece etc.
Use the correct Subaru intake.
If/when your friend gives you the new turbo and other parts you are talking about in the other thread, do not use the Injen intake. Sell it or something, store it, whatever.
When you buy the AP look at the map notes for parts that are supported. Do not deviate from those notes. Your Subaru intake is great for your needs. Everything else has simply generated problems.
Yeah its the same one. Im taking it off tomorrow, Ive been reading further in the threads and have only become more worried. I think the company i got it from is going to be refunding me so thats good. I read somewhere on here that buying a ebay tbe would be no dif than a name brand one so i figured same concept could be applied to the intake. Noob moment. Also i bought this car at 83k and after becoming more familiar with it im almost certain that it was modded previously and not restored to the factory tune after the parts were removed, any way i could tell for sure, and if so how would i go about getting the factory tune?
No. Just ones that use Opensource software. Maybe post in the regional forums and see if someone with a Tactrix cable would be willing to pull your ROM.
Just finished putting the stock box back on and am pleased to report that the CEL has disappeared. So even if i were to install a Cobb or SPT intake would i receive the same issue without a supporting tune?
I want full bolt-ons with the cobb AP done first. After that ill be getting my friends STI turbo w/ top mount, and it will be a little while for me to save up to get everything ready for that. So i want some kinda power before then.
If you're ever in the DFW area I would gladly pull your ROM and take a look at it. At the very least it would be a good idea to log and see how it's running. And if you need different map flashed I could do that for you.
Well the AP only supports two intakes, Cobb SF and AEM.. read the map notes before you just start buying parts that aren't supported.
Besides that, I don't think the intake maps make any more power than the maps designed for the stock intake. So wanting power is no reason to be spending money on an intake anyways. You should be getting a protune if you're interested in power gains.
Maybe i'm missing something so forgive me but, i though intake = a lean mixture not rich. Is the ecu richening up the mixture to compensate that much to affect fuel trim by 20+%. And if i was a rich mixture i dont see how cleaning the injectors would help because dirty injectors would also cause lean mix.
Im either lost out of my mind or completely wrong lol
Depending on the intake it could cause the car to run lean or rich. The problem is that they can skew the MAF readings, in either direction. If the MAF sensor is reading higher than it should the car would run rich, and vise versa.
