Engine issues

[novacircuit]

Okay so I'm still having some pretty serious issues. I fixed the line and there are NO leaks. I pressure tested and everything is clamped up tight. When i cold start my car will stall and idle extremely rough for the first startup, but every other startup is fine if the car is still warm and after i drive it for even the smallest distance the idle is fine. My car putters out in low rpms at times (at least once each drive) under 3000rpms. OBDII scanned and got these coded:
p2177
p2187
pending p2177
pending p2187
pending p2097
pending p2195

the first two are engine bay running lean and lean at idle and the last two are front oxygen sensor issues; however, since they're only pending i feel like the first two codes are causing errors with the oxygen sensors every now and then.
Like I said before I only have the cobb sri. Could the sri be throwing off the sensor and screwing with the afr?
Any help would be greatly appreciated.
Thanks.

bump for help anyone?

there are like a million vacuum hoses in this car. did you go over all of them?
running lean means you're sucking in air. do you have a way to monitor afr?
did you tighten ic tubes or couplers? tighten intake couplers? tighten your inlet? make sure the recirc hose is actually tight.

Try putting your stock BPV back on and see if things settle down. If so, your BOV is either defective or not correctly installed or adjusted.

Something still isnt right, you sure the BPV is adjusted right? check all this^^^ also. you might wanna just start from scratch. Take everything you installed off, look around make sure everything is ok, and reinstall, but being careful this time. You might find something right in front of you that your missing. reset battery again, and test.

The issue your having sounds exactly like when i forgot to hook up my recirc hose the other night. Cut on, run for a sec n shut off, unless i held the gas for it to idle for a second and level out, but as soon as i gas it gas to move it would choke and almost die out.

hmm. After doing some more research, running over the codes, and checking stats on AP I think I might have a bad front O2 sensor. Do these symptoms seem indicative of a bad sensor? When i check real time AFR on AP there is no update. Every now and then it'll start logging and it'll stick around 14-15 (good) but only rarely.

......... that would be one hell of a coincidence bro, did you check the wiring for it? if you crawl under the car the plugs are on the drivers side of the bottom portion of the motor, you could make sure the plugs are in all the way. one is grey and one is black, but splits into two different plugs. The two different plugs is your primary. You might already no this but if not now you know

someone else might wanna chime in on the 02 sensor part, i havent had an issue with mine. i know how to take em out and were they are but as for what codes they throw i have no clue

hey what year is your car? you might wanna check this out:

took my car to the dealership and hot it checked. Look at OP for update

 

[MSMS3]

I feel like I'm running in circles going back to the OP and now back here to post a reply, but I understand the reason for the edit.

Since the problem was the fuel pump, they replaced it under warranty? See if they'll give you the old one They probably will just throw it away.

You could use it as a core for upgrading the internals. They don't need to know why you want it!

It's cool they didn't hassle you on the mods, especially the AP. I guess they did not.

Glad you found the fix. With a little luck you can drive with your new fuel pump while having the old one rebuilt for high output.

 

[RC08MS3]

bro, those two parts caused the pump to fail? that wasent something i thought of lol, i would've never seen that coming. i just installed my internal kit (for the second time due to the recall) and it is probably a decent investment. glad you found the fix though, seemed like we had you running in circles

***Final Update***

So since my car was still considered under warranty with it only being an 08 and only 12000 miles i took it to the dealer service dept to see if they'd honor the warranty with the intake and bov on. Turns out they are pretty oblivious. They said they couldn't get in the ecu (AP), since i forgot to unmarry like an idiot, and i came up and uninstalled it at the service dept.. anyways they found out it was the engine pump failing... so how does an engine pump fail from just an intake??? ridiculous... and as for the ap i had the issues with the pump before i installed ap so the ap didn't cause the fuel pump issue. So my question, should the new pump be pretty solid for a few more mods or are new internals essential? i was planning on getting them pretty soon anyways but just seeing what everyone else says.
thanks

I recently installed the cobb sri and a greddy type s (recirc of course) on the speed3. At first there were no issues but i realized later i forgot to modify the hood or rotate the bov to fit under the plastic hood molding and now theres a hole in the turbo tubing to the bov. I tape this up about every other day (doesn't hold long...) until my silicon tubes come in. Now, a couple days after the installs i get a check engine light (around the same time the hole was created) and at startup at idle the car will putter out and shut off. This only happens right after startup and after i drive and am at idle at a light or something there are no issues. Also, every time I drive the car now i get fuel cutoff at least once. Any help or suggestions? thanks.

Stock internals have generally been estimated to be good up to 350 hp (at the wheels I think, its been a while since I have read up on it). Its pretty common info if you search for it. but you should be fine for an intake and a few more mods.

Just an FYI for anyone that has similar issues in the future and looking at this thread. The tech at the dealership had called and told me he replaced the fuel pump and purge solenoid valve... so I assume these parts were causing the issue. Turns out, as soon as I turn on my car to leave the lot it stalls at idle twice... I talk to a different tech that is more up to date on the speed3s and he tells me to bring it back. I bring it back and he replaces the front O2 sensor (as I originally assumed.....) and cleaned up the spark plugs, which was interesting because I had just replaced them. Maybe dirty from running so lean? But anyways just wanted anyone looking to know these were the symptoms I got and the issue with the car.
