Well a little update. I tried reinstalling the rear o2. Nothing different.
So, I got in the engine bay and put Zipties on EVERY vacuum hose where the hose goes on the nipple. Now keep In mind I didn't have any leaks according to brakleen and propane. But........
My STFT's and my LTFT's are back at 0
+/- 3....... Guess I had a leak at one of the lines that didn't show its face to the torture I put it through. But leaked just enough to screw up my fuel trims.
Sounds like I'm getting some zip ties!!!! Whoot, hope this works for me!!!!!
I did notice a couple of my vac lines were more snug then tight fitting so I'll try and see!!! When I redid my vacuum lines I just used hoses slid over the nipples. I'll do that this coming week and let you know if it worked for me. I got my 2.25 band clamps for my cross over pipe and I have to replace my rear valve cover gasket. I'll do all that at once.
I'm a little in the negatives but that doesn't concern me unless they go farther than 6%.
I still don't know which line was leaking.
Don't forget the brake booster hose
Zip ties didn't work.... :( I'm leaning toward supercharger gasket. I hear an air sound from the middle of the supercharger area, behind the oil filler cap although if I soak it with carb cleaner it doesn't change engine revs what so ever... Spray was bubbling on the LIM though, thought it was cracked, but was just from heat because it did it everywhere.. :-/ I'll get a fog machine and test it before I dig to much more...
Broke down and ordered a fog machine today... Should know more next weekend..
I haven't had any luck either now instead of locking in at zero at wot its going to 12.5 but while cruising up to speed it'll be at 5.6.
Mine is actually starting to act up again. I'm in the process of getting my PCM checked by reptile. I'll let you know my findings.
Cool thanks, hey by any chance do you know what pin to bend to put the fuel pump on high mode all the time?
Sorry to hear yours is acting up again... This is REALLY annoying... I hope to find something fairly easy with the fog machine. If I do, you all can bring your cars to me and I'll check it for free.. LOL Twizted might can do that, I'm in Chattanooga...
Sure do. Lower left pin on top left relay.

Ok cool thanks, cause my ltft are lower while normal accelerating but jump up when wot to like 8.0. Have you guys checked if your evap is stuck open?
That's something I haven't checked.
I need to take a look at that when I get home today.
I borrowed a Fogger from a friend of mine but it took a dump last night.
Didn't even have time to use it.
Might be down for driving to chattanooga for a day of diagnosis! Lol
I think I may have to get a fog machine and try again, this code really is a pain in the ass haha anyone getting slight kr spikes while driving?
Damn right it is! Haha
Not while cruising. That sounds like false KR. You may have something rattling under the car causing that.
Well it'll jump up to like 8* sometimes when my car doesn't want to shift to third because of that skip shift tune so it wants to stay in second. And sometimes when I get on it it'll jump but never stays if I let of and go again it'll read 0* maybe its cause I'm running straight headers right now and everything rattles lol, def need exhaust finish soon.
Dayum this code!!! lol
Luckily I'm not seeing any KR, but it is pissing me off. Heck yeah, come on down I'm game with beer..
How can one check the evap? I unplug the large vacuum line from the port on my N* and NOTHING changes... I don't even feel any vacuum off either end... I wish I would have had my evap stuff deleted out of my tune.. :(
I'm not, I think if its stuck open it'll pull vacuum through but I can't find the post I seen.
Ok, been doing some more testing.
I actually just snugged down my TB bolts a little extra. And checked all of my LIM and SC bolts to make sure they were Tight.
Now when I'm cruising or idling the ST < trims are fine, But......
When I let off the throttle the LTFT'S spike to +16.4 until I either come to a stop or give it throttle!????
Now I'm lost for sure! Lmao
I've been in contact with brian about another PCM and should have one on the way shortly. I'll post up my findings once I get it swapped in.
Currently I actually have a similar issue. Sort of waiting for someone to look at my tune to see whats going on. That and I plan on doing heads/e85 soon so Im not overly worried about it right now. But with mine...
Runs great cold/warm. Totally normal LTFTs. Tons of power (spin tires at 50mph type power).
Once it gets to full temp (180-195) for a minute it goes to hell. Massive drop in power and my LTFTs are 16.4 at idle and as soon as you give it any gas it goes like -19. Cruising LTFT is also adding tons of fuel.
Also at idle when its adding tons of fuel you can smell fuel strongly through the air vents. Do you get that? No one can find any vac leaks. No trouble codes.
Its almost like my PCM goes into a different tune mode when it gets to full temp... I've been watching this thread to see what your solutions are to see if I can try them too.
It's a mystery to most of us so far... LOL Mine is progressively getting worse so I know it's a vacuum leak. I can actually hear a hissing sound now between the number 3 and 5 injector so I'm leaning toward my supercharger gasket (even though I spray carb cleaner and propane and NOTHING). As long as I give my car gas, it's fine.. As soon as I let off the gas it rumbles and pops (backfire but not like an actual backfire) then it will smooth out.. Very weird. But my fog machine was shipped today (I used the free super saver shipping.. :-/) so I'll get it middle of next week. I hope to see the fog coming out from under the supercharger where I hear the hissing and NOT a cracked housing or LIM. I'm eager to get this fixed so I can drop pulley some more..
Check your EGR tube and all your vacuum lines. But if it only happens at OP temp, that is odd.. sounds like something tune related, or part related and the heat opens a crack more?? Dunno... Hopefully once we find what's up with our, it will give more options to others.
I'll post pics and videos once I start playing with it. What I have to do is:
1. smoke test the car
2. replace rear valve cover gaskets (stupid zzp gaskets)
3. replace the 2 2.25 clamps on my cross over pipe with two 2.25" band clamps I now have
4. hopefully replace the supercharger gasket and fix my P0171 code lol
5. install my new tips... Ready to get my car's azz looking better... :D
