Question 98 camaro wont idle or hardly run

ok i got a 98 camaro m.s. v3 stock except valve train. ok my car for the last 2 months wont idle (it surges then dies) lost all kinds of power! then the other day it started missing, so i changed plugs ,o2s and clean MAF, ran better but still not the same, it did quit missing but still lack of power? any suggestions? o and today 3 weeks later the miss has started to come back, u can run it wide open and will clean up but then not 2 mile down road back to missing?

have you tried to clean the throttle body? my 03 GMC did the same thing and after I cleaned the throttle body, it ran like a champ.

well i kinda thought that myself it has some apoxy job on TB so that was my next option, but i did find a bunch of small vacuum leaks so i pulled inake last nite putting new intake gaskets and will see if that fixes it? so what im thinkink is that with the vacuum leaks it is throwing a lean code and overfueling it.

ok got intake back on, all new gaskets it ran fine up until it got to normal opperating temp, then i blasted it (WOT) and it ran good then i made it about 2 miles and it went to loading up and idle surging. so pretty much as long as its on the floor it runs good but wont idle around town?

Ok i do have one other problem but its very small, ok after anithial warm up (say u run to the store) then u start it and it will flutter or start to miss and if u clean it out then it will go away. untill u shut it off again. ( its almost like the o2s get a coat of suoit and dont read then u blow it off and its all good. Or somebody told me that the bosch o2s are bad about reading cold?
