Default tweaking idle - slight heistation

hi all - i've been fix some things on my car and now have a slight idle issue when the car is in drive with the brake pedal pushed...it is all started after a fixed my vacum leaks...so the car idle's fine, but when i am at a red light and start to hit the gas it heistates a little bit before she gets moving...it doesn't come close to stalling out, just the RPMs drop a bit, and it is very noticable...any ideas what adjustment i can make to compensate for this?

Check the accordion hose and the smooth rubber hose that attach after the air flow meter and to the throttle body for leaks. I had free air coming in there that caused much the same thing. On the accordion hose, look down in each crevice.

actually that was one of the areas i fixed...although it is pretty rotted out and i ordered a new one from jagbits...i also have more info, the issue goes away when the car is warm, so i am pretty sure it is the temp sensor that is telling the car it is warmed up when it is not...does that make sense?

Yes, it does....it would cause a lean condition....sorta like an older car where the choke wasn't working right
