Slammed05 Posted May 7, 2017 Author Share Posted May 7, 2017 Not really a update since I haven't gotten my sti fpr in the mail yet But I did notice while driving the car yesterday and getting into full boost, my boost gauge is no longer accurate at all, I know a few people reported swapping the vac lines and putting their boost gauge line into that 4th runner and seeing fluctuations, but it is most definatly confirmed that my boost gauge is all over the place now lol Link to comment Share on other sites More sharing options...

Sent from my LGLS755 using Tapatalk You guys can tee both the gauge and the FPR into the same location and just cap off the cyl #4 nipple. That line will be more unstable since it's got the pressure fluctuations of just one cylinder instead of all 4 averaged together. Link to comment Share on other sites More sharing options...

Slammed05 Posted May 10, 2017 Author Share Posted May 10, 2017 Most definatly did not fix jack shit, maybe made it better, or happen less often, but still happened to me again today Link to comment Share on other sites More sharing options...
IllRad Posted May 11, 2017 Share Posted May 11, 2017 It doesn't really go away. Just makes it better. Idk if anyone has found a permanent solution for this problem. Sent from my LGLS755 using Tapatalk Link to comment Share on other sites More sharing options...

FJuan Posted May 11, 2017 Share Posted May 11, 2017 Did you reset the ECU to let it recalculate? My wife's balls are delicious. Link to comment Share on other sites More sharing options...
Slammed05 Posted May 12, 2017 Author Share Posted May 12, 2017 Yup, I reset it, car idled for a solid 20 minute before it was drove, the battery was disconnected during the entire install to ensure it fully got reset Link to comment Share on other sites More sharing options...
solidxsnake Posted May 12, 2017 Share Posted May 12, 2017 Yup, I reset it, car idled for a solid 20 minute before it was drove, the battery was disconnected during the entire install to ensure it fully got reset Just idling won't help the car learn. Once it's warm, it will learn how to "idle" very quickly (a minute or two). Actual driving is necessary for the ECU to learn various conditions after a reset. After a couple days of normal, varied driving, the ECU should have stabilized on its learning assuming the car is mechanically sound and the weather hasn't changed drastically. From my understanding, the stumble is helped by the FPR/reference line mods, but also heavily influenced by tune. Without logging it's really hard to say what the cause is or what can be done to fix it. Link to comment Share on other sites More sharing options...
Slammed05 Posted May 13, 2017 Author Share Posted May 13, 2017 So today the car would only hit 8psi car is tuned to hit a peak of 19psi, and was doing the typical sputtering, I get home, not even a hour later I leave, and the car hits peak boost (19psi) Link to comment Share on other sites More sharing options...
Slammed05 Posted May 24, 2017 Author Share Posted May 24, 2017 So I found 2 boost leaks, one on the ebcs, and one on a purge Solenoid, replaced both if them and the problem is still there I'm wondering I've I'm just chasing a ghost at this point, no cel, it really only does it when the engine is cold and not at operating temp, but I'm officially lost, maybe something internally? I read somewere that people forget to put a O ring on the top of the fuel pump (which I recently replaced mine with a dw65c, but the problem was there before I even replaced it anyway, and I'm 99.9% sure I put the O ring in place anyway) Link to comment Share on other sites More sharing options...
Slammed05 Posted May 24, 2017 Author Share Posted May 24, 2017 It also really only does it for a second or 2 Link to comment Share on other sites More sharing options...
IllRad Posted May 27, 2017 Share Posted May 27, 2017 Mine only does it on cold starts too and when under heavy-ish load. Doesn't really bother me. Sent from my LGLS755 using Tapatalk Link to comment Share on other sites More sharing options...
Slammed05 Posted May 28, 2017 Author Share Posted May 28, 2017 Thing is 50% of the time once the car is fully warmed up it'll kinda drive weird, it'll litterally feel like some things clogged at times, only other thing I could maybe think of is I have a injector tick that seems to be a lot louder than most people, but I have no idea how to physically check if the injectors may need to be cleaned or anything Link to comment Share on other sites More sharing options...
HAMMER DOWN Posted May 28, 2017 Share Posted May 28, 2017 Mite of missed it, but have you tried fuel injector cleaner. I had really bad stumble between 3500 &4500rmp's. A bottle of fuel injector cleaner, cleared it up in less of 1/4 tank. My injector are original & never been removed. But if I don't remember to use fuel injector cleaner at least once a year, the old girl like to reminds me of my neglect .

Slammed05 Posted May 28, 2017 Author Share Posted May 28, 2017 I have never ran fuel injector cleaner, honestly always thought that type of stuff was a gimmick Link to comment Share on other sites More sharing options...
HAMMER DOWN Posted May 28, 2017 Share Posted May 28, 2017 OK, nothing more to say, good luck. But if you like to try, here's the three I recommend. Techron® Fuel Injector Cleaner Berryman® B-12 Chemtool AMSOIL P.i. I been using AMSOIL P.i. for 12 years (314k+). At least once a year & never had a injector problem, when I remember to put it in.
