Stumbling and stalling !!!!

[HolleyWood]

ok i have a 92 geo tracker 8val

well i thought it was the timing but im not sure it is

well i turn on engine and it stumbles and stalls when i give it gas

and it will not idle lol

ok when it warms up it will idle but thats about all it will do

then when i give it gas it bogs and shuts off but theres sometimes

it will get a good hit sometimes but then it goes back to bogging lol

well i stoped the timing by jumping the c and d on diag plug

didnt do anything so plz help

hi Idles HOT ONLY 8V.

THE C&D jump is only to FREEZE ECU igntion timing so a human can set the igniton timing with a timing light.
nothing more.

when was the last tune ,up,
plug,wires, cap and rotor. ?
