Another idling issue?

So hears the deal .When i give her hell and let off ,everytime i come to a stop it wants and does sometimes stall ,acts like its flooded up.not under normal driving conditions,only when i hammer it.Hears the weird thing,and i dont know why ,whenever i put gas in the truck and take off itll do the same thing.weird.Its been doing it for a long time,i just been dealing with it but now i dont even want to drive it its so annoying.thats y ive been doin body work and stuff and driving the h.d..And also the other thing is idk if its related or not but when it starts cold its the same way till it warms up after like 2 minutes.but if i try to take off right way in the morning it acts like i left the choke on.I know it dont have a choke.lol.to me it seems like its flooding up.but idk ,with this new stuff it could be lean idk.Im thinking maybe some sensors or something ,i really dont know what to look for.I have good fuel pressure 60lbs all the time.no CELs.the motors a 08 with like 5k on it.always change plugs /wires change oil ,run 93 octane and most of the time octane booster.o2s are fairly new.Im open for suggestions or questions ,thanks guys.Allen maybe you can tell me this, could it be the tune with this cold weather up here as far as the morning startups?

boy ,quiet on here tonight.3 hrs and nothin.lol.

I read your post, but am clueless on an answer. Sorry im no help. :doofus:

I've had a similar problem.. not all the same but similar it's my cat now I think I've blown it out enough i haven't had to deal with it for awhile but i've got the cat rattle..

Now that I think of it I have heard of this before. Idk if its your problem but I read that the intakes will warp and cause a vacumn leak. Dorman makes an aftermarket replacement to fix this problem.

could your fuel pump booster controller be putting out too much volume for the system to handle? Coming on too soon? Check the vacuum switch too.

The manifolds don't warp even though they seem like they would. The gaskets leak...A LOT. I have one right now that's half way done. 2004 Yukon 150K miles.

speakin of is there a spec on those manifold bolts?? I looked all in the book can't seem to find it.. I've just kinda winged it the last 2 times i took it off

I dont have the boost reference line on the regulator .unless your talking about the electric controller box that keeps it on low until certain rpm for the f/p?ya know ,maybe its boostin the pressure that 5 psi to quick then i let off?and it has that shot of gas in it.What vaccuum switch red ?ya know ive tried talking to aeromotive b4 ,but they think theyre products are the best in the world and dont think it could be them at all,last time it was theyre regulator.I wish more people had this setup like mine so we could learn together on it.

OOOOOk then, lets delete the part about putting gas in the tank and go from their ,just go with the part about wanting to die when i get into it then let off.
