Help! My Car Is Stalling! Need Help Asap So im selling my 99 transam with headers/cb/lid/underdrive pulley/rearend that has 108000 miles on it.and i have a guy wanting to buy it tomorrow with cash but now it just HAS a f'n problem. When i accelerate or give it gas, it SOMETIME wants to stall out. But if i put it in N, start it back up, it works perfectly. it happens only once in a while, never at cruse, only when i floor it. it hasent done it in like 3 days but now its did it 2ce comming home. its like everytime i accelerate hard it seems like its starved of fuel and wants to stall.. it use to do it on start up but now its doing it when its warmed up.
i need help fast to figure out what it is. no codes being thrown and oil pressure is fine. HELPPPP pleasee!!!!
i think its a fuel problem. could it be a clogged fuel filter? maybe clogged injectors? i dont think anythings broke because it runs fine after it does it, and it only does it sometimes.

no codes where thrown when i put the headers on and deleated the cats no codes were thrown either so i think it was tuned b4 me, the guy b4 me replaced the rearend and had a hole drilled in the side of the TB, as well as running 2 degree colder spark plugs..
im reading a few things..
fuel filter?
vacum leak?
exhaust leak?
o2 sensors?
MAF sensor?
ground wire disconnecting form heads? i donno really what that ment but one guy on here at that problem..
any of these be the problem? this guy wants to look at it tomorrow and i cannot take it there like this..

replacing the fuel filter is a good start and isn't much work to remove either, you got an auto or stick transmission?
why did that guy use colder plugs? stock our plugs are a hot plug, imo i'd change to trg55 spark plugs regular ones

update:
fuel filter changed. added a fuel system cleaner, (possible clogged injerctor?) going to change the oil and add a fuel stab. mob1 10w30 oil mob1 oil filter, lucus oil stab. and lucus fuel stab.
didnt notice the problem but i only drove it for a few mins.
i had a fuel pressure check. when key is on it is at 48. and they told me it should be at 55-60.. could that be the problem!??! i was told a 5psi change is enough to do that..... so could it be fuel pump? even though it runs fine?
and i did change the plugs to those plugs when i did the header change. and it is an auto
