94 k2500 5.7 tbi 4l60e just did head gaskets swapped to edlebrock performer intake ultimate tbi mod injector spacer and throttle body spacer. truck wont run at 0~timing runs best between 4 and 6. unknown Miles on engine but odometer says 280. so my issue is that there is a intermitent miss and hunting idle, missing power through the powerband and kinda stumbles in the higher rpms at wot aside from that it starts first crank and runs great ish
replaced 02 sensor, plugs, tps, and rebuilt tbi unit. has the 96+ fuel pump @30 psi. with upgraded spring no afpr.
I've been fighting this thing since it went back together and I do not know where the timing was set before headgaskets
any thoughts? cap rotor and wires was done about a year ago but thats probably my next move.
