And you should just delete all your EVAP. That's what I did with mine. It's just more lines you have to worry about leaking. You'll get an engine light, but that's easily removable if you've got someone that can tune in your area.

You are right, I should have.
It's something quirky not tune related I'm thinking now.... great.... LOL

I'll have to pull the evap off then cause it didn't work. Now my ltft are at 16.4 then lower to 7.8 at idle. Still only making 4psi when I was making 6.2
07-10-2013
Keep spraying around man, you'll eventually find it if the blower gasket didn't do it for you.
07-10-2013
You find out yours yet?
07-10-2013
Nope I haven't found anything out... lol I was out with propane (probably not the best but) and carb cleaner... I was even pulling vacuum lines off and back on seeing how the car reacted and what my boost gauge would do...
I'll order my band clamps tomorrow for my cross over.. I think I have a small leak in the cross over, which might can cause this to.
07-10-2013
I might have to check my crossover out.Im thinking about trying the seafoam.
07-10-2013
I need the band clamps regardless, the clamps I have on there now suck... lol I used band clamps for the DP...
I'll use seafoam or I'll buy a fog machine... they are fun and amazon has them for $25...
07-10-2013
I heard some stuff about the fog machine leaving a sticky residue or something I'd look into that a little maybe.
07-19-2013
Have you found out what was wrong with yours?
07-20-2013
Not yet...... I'm getting pissed at it... lol I rode in my buddies car today which is a bone stock 97 GTP and his LTFT @ idle were where they are suppose to be but when he took his foot off the gas they were going to 20+.... Mine never go higher then 16.4 and I trigger a code.. :-/ With this said, the P0171 code calls for a bad O2 reading... now I'm leaning toward my crossover. I'm getting 2.25" band clamps sometime this week so I can get rid of the POS ubolt clamps on there now and going from there.
I went to a buddy of mine, big LSx guy, and he said the regular fog machine will work fine... He said he's trust it before he would seafoam... So if replacing the cross over clamps don't fix it, I'll get a cheap fog machine...
Now one question, if you've done it while looking for a vacuum leak, have you removed the large vacuum line from your TB? I think it runs to the EVAP. I removed mine and I have no vacuum coming from the nipple or line and the car doesn't act different. Before I top swapped, if I pulled that line off the TB the car barely ran and just sputtered.... Is it the same with Supercharged cars? I'm wondering if when I did my N* swap, I didn't trim out my gasket right and I'm sealing that port up causing my EVAP to not work properly. Probably not, because no code, but was wondering. I mean I can pull that line off and my vacuum doesn't change at all on my gauge and that should cause a huge leak....
DANG CODE..... LOL
07-21-2013
I know I hate this code haha. Now I get knock off an on and lost boost idk why's this so difficult...

Stupid code... LMAO Does yours stay on constant?
That sucks!!! Luckily I'm not seeing boost loss, KR, or really any "performance" loss just LTFT at idle out of wack and fuel mileage sucks...
Still wierded me out with my buddies jumping to +20...
07-23-2013
My LTFT's are at 16 when idling and when coming to a stop at 0% TPS.
when I'm cruising the LTFT's stay around 5 and the STFT's are around 0.
I have a DHP tune, 2.5"downpipe and opencone. I'm also getting 3-5° of KR at Wot. Hoping you get this figured out and maybe I can figure mine out as well. Lol
I've fogged mine with no leaks. I've coated it with Brakleen while watching my Scanner. I've tried propane to see if it would affect it at all and I'm at a loss.
All of my symptoms came back shortly after fixing the EGR tube. ??????
I'm stumped. Also I'm getting no codes. My cat and rear o2 are also deleted. I wonder if the rear o2 being gone has something to do with it??

My rear o2 is unplugged too. The code is deleted from the computer. I guess ill see when I get my exhaust done.
07-24-2013
Its deleted from mine as well, but every since I removed the o2 sensor my LTFT's have been High at idling or decel.
Just wondering if it might have an affect on it??
07-24-2013
Hmm.... Mine is the same. Rear O2 was deleted from the tune and I have no cat.
Twizted, do you have headers? I figured it had something to do with moving the Front O2 18'+ downstream...
07-24-2013
Not yet. I'm going to put the rear o2 back in either today or tomorrow and see if it makes a difference.
The tunes don't Actually delete the sensor, they stop the PCM from constantly monitoring it and setting codes. (I think)
My gas mileage isn't bad. Averages 27mpg. I just don't understand the high LTFT's at idle and decel.
07-24-2013
Let me know if that works, ill have to hurry and get my exhaust finished.
07-24-2013
Will do.
