Default new sti owner with issues (pls help)

i recently purchased a 2010 blue hatch with the gold bbs wheels. and feel in love with it imediatly. however on my way home with said car the dash lit up, so i took it to advance to get the codes. the codes came back as 0852 or park neutral switch high current and i think the other one was 0171 or bank one reading lean. car was put into limp mode so i imediatly drove it back to the dealer. 3 days later i get a call all is better come and pick up the car. needless to say after a certian amount of miles this happens again. so i have had the car in my possesion for less that 5 hours total and its needed to go to the shop twice. but here is my question. the car has obviously been somewhat modified. its got an SPT intake and an Agency power cat back exhaust system. im assuming the previos owner had an AP but probably reset everything back to normal. is this possibly what is going wrong with the car. im beginning to think it is. but i just want to make sure. if so why would this cause the 0852 code. any tips or advice. im heading back to the dealership right now.

Probly not a bad idea to get a tune for that intake as it can cause subarus to run lean with out a tune. I assume you are correct and it was modified and had a ap on it and the previouse owner unhooked the ap and left the mods on causing issues.

THere isn't an SPT intake for the newer gen cars. So that intake may not be designed for the car to begin with. I'd try to swap back to the stock airbox to start with. Does it have a downpipe on it as well?

^^ This ^^ It doesn't matter if the previous owner had an AP. The intake on your car was designed for previous generation WRX/STi's. Why it's even on your car is beyond me. Follow what the guy above said and get a stock airbox. Check too if you have an aftermarket downpipe installed too. Those two mods in combination with the already ishty stock tune... Get that looked at and fixed ASAP!

so mods are as follows.

1. AP intake
2. ap cat back exhaust
3. perrin down pipe

it has a brand new stock ecu and the dealership is telling me it may be the turbo and there going to replace that with a new one next. but i plan on taking it to get it open sourced tuned in jax asap...

^then your car is not tuned for it you need a Cobb AP for your car to tune it for stage 2..i would suggest not driving it till you have done that or put back on stock downpipe

chances are the tool flashed it back to stock map before he gave it to the dealer and did not say anything so he could get a extra $450 out of hte deal by selling the AP


*edit jk..hurry up and get opensource if thats your plan then because right now your not tuned for that downpipe WHY has a subaru dealer not told you it has a non factory downpipe with a stock ECU and that could be the problem :S

I would find some friend with a tactrix cable, downloaded the maps from the car and compared it with the stock maps to see whether there is any difference. Basing on this it would be able to decide how to handle the non-stock intake / DP issue

Cobb stage 2 cannot be ran with the AP intake. He needs a tune specifically for his intake, and Cobb doesn't offer maps for it.

Getting a new turbo? Score! Now, when you get your car back, baby the friggin hell out of it! Do NOT open the throttle and go into boost EVER, until you get tuned. You shouldn't drive around at all, so if you can talk to your tuner, ask him if you can get a limp map so you can safely drive it til you get the proper tune.

having a cobb stage 2 will help him loads more then if he has no tune..on top of that with carfull data logging it may work anyways just fine it just depends

I believe it was illegal for the dealer to sell you a car that had all the factory cats removed. Not being tuned with that intake and downpipe is 100% sure what's causing the issues. Find stock parts for it, or get it tuned ASAP.

so the dealership said it should be fine to drive just try to stay out of boost. i have already talked to a tuner but they are about a 5-8 hr drive away so im just going to baby it untill then. im dropping it off at the dealers in a couple of days. fingers crossed. and yes i totally agree with what was stated about the guy removing the AP.

Wow thanks for the needed input miss obvious. That was truly a much needed statement that will truly be helpfully to everyone.

Anyways. If it wasn't so clean and the head tech at the Subaru dealership( not where I bought the car) hadn't said it appeared to be a well kept unmolested sti I might agree with you. I still stand by my purchase at this point. I think it just needs a good tune as it does have stuff to help it breath. I'm trying to be optimistic at this point lol. My other car is an rb25det swapped 240sx convertible that I swapped about 2 years ago so I'm not entirely mechanically stupid only new to this platform and always open to any HELPFUL advice.

ulll be able to sell it, I have a sti 05 that's like 80% modified or more, had it for 6+ months and haven't had anything major happen-- the previous owner even gave me the ap with all the tunes that he got from PDX tuning, the purchase was pretty much a steal for a $40,000 when it's brand new lol
