New(used) STi, Major Maintenance Questions, Weird CEL and well, even datalog fun!
You're right. I'm trying to build Rome in a day here and I got caught up in the excitement. I think I'm going to go for the DWorks pump, TGV deletes, meth/water injection and a Protune to tide me over for now. I'm not so hot on the Greddy Evo2 exhaust and Cobb downpipe. I'm consider a true 3"... -

The intake got here today and I installed it right away. The idling issue still persists so I'm going to hit up Rek for a MAF to check that off. I really appreciate y'alls time and expertise! -

Yeah, I just got done reading many reviews/install/notes on the topic. Good to know, good to know. I talked to Cobb in Plano and they said that TWG, TGV deletes and fuel pump won't do much to improve performance due to the small turbo. What is your take on that? It sounds to me that you guys... -

Ok, awesome. So I understand now why some go the EWG route and just have Port and Polish done(for example by Grimmspeed) and they get the Xpipe as a package deal. Man, it is so hard to not just go all out and buy all this stuff. But I still need to replace the timing belt and do some other... -

I wanted to pry y'alls brain on the whole headers/uppipe deal. I'm pretty confused as to how they all tie together. If I wanted to go with the EWG setup, I couldn't get headers? I've noticed headers come with a builtin uppipe for the most part. I'm not exactly sure of the functionality of it... -

Alright! The intake should be coming in sometime today. I will report the results! I did the boost leak test posted on that link combined with all the other tricks and I couldn't come up with anything. If it isn't the intake or MAF sensor then I will have to do another boost leak test, maybe... -

I cleaned that MAF at least three times while I was trying to troubleshoot the issue. I also used some electronics cleaner on the connector a couple of times to clean the connections. I just never figured that it was the issue! I appreciate your generosity! -

Here is what I found: I unplugged the MAF and it idled at around 800 and IT STAYED THERE. Now, I'm a little sensitive to what a good idle is supposed to sound like but I mean it felt pretty steady. There was no up and down rough feeling anymore. Anyways, a picture is worth more than words(in... -

Update: I pulled the O2 plug. Assuming I pulled the correct one. I pulled a plug with an end connected to the engine. It was covered in a blue covering and it looked like an O2 sensor. Anyways, when I pulled it I got a P0031 code so I think it is the right one. When I pulled it and started the... -

I will try this right...now! Do you mean on the engine or under the car? -

Wide Band AFR Gauge is on that short list! I know! The first thing I checked was the size. It can be found inside the intake where it connects to the inlet. It is the same one I ran when I had my other STi and never had such fuel-trim problems. I know that they make a 70MM one that NEEDS a tune... -

Yup, just saw that. So would I be able to get the Grimmspeed UPP with headers? I'm confused as to how this all ties together. This is probably as far as my mechanical know how of engines go. -

What do you mean "crosspipe and collectors"? I know what a crosspipe is, but collectors? Edit: I thought crosspipes were a complete waste. Many go to the PnP work instead. What are your views on this? I currently have the COBB DP and Greddy Evo2 exhaust. I had a Tanabe TBE (blue-tip) on my old... -

Wow, I definitely spent the last two hours at work just fantasizing about how she is going to purr when all is said and done! I guess there are somethings I overlooked, like gauges and controllers! It all sounds so fun! I've seen the DIY for the TGV deletes. I think that is something I can... -

Awesome: So in summary, injectors and TMIC are good for now unless I'm ready to upgrade to a bigger turbo. In order to setup for such an upgrade a good up-pipe(or a EWG kit, that Grimmspeed Ceramic coated 38mm EWG one looks sweeeeeeeeeet) can come up handy as well as a set of headers. This will... -

Excellent information. I'm going to take your advice and upgrade to the DWorks fuel pump. Just a quick question, when you say that injectors and TMIC are ok, do you mean as in upgrading those? Maybe getting some DWorks injectors and a bigger TMIC? Or do you mean keeping the stock injectors? Is... -

I wish I could help you out more. I mean, for all I know that was a total BS statement. The power of the internet. I'm not trying to achieve 400whp, it would be nice though :D I know STis are super picky about what goes in them. Which is great b/c I love spoiling the women in my life! LOL My... -
What name do you call your STi.
The first one was named Jasmin. My current one is named Selena. -

So while I play the waiting game for the intake, I'm looking at a fuel pump b/c I'm replacing the fuel filter and I think this would be a nice and cheap upgrade. I have started thinking about potential mods to improve performance before my first tune. The farthest I've gotten was Stage II so... -

Awesome! And thank you for the tips about dealing with the stripped screw from hell!
