Re: 1991 chevy 1500 5.7 tbi erratic idle

so i have my anniversary coming up and my wife is going to buy me whatever I want and it looks like its going to be parts..... when we did the intake gasket the egr passages were completely clogged with carbon, obviously we cleaned them out think its safe to assume that there is a lot of carbon build up in the egr iself? also would the egr cause low vaccuum at idle? and if I recall correctly when my mechanic was checking timing I dont think it changed after the est wire was reconnected, what would cause that? the knock sensor wasnt hooked up for some time, is there a way to check this? here are all the new parts already in.... themostat, o2, plugs , wires, cap, rotor, icm , coil, cts,intake gaskets, tbi all new gaskets and cleaned, tps , map, and iac ,

heres what I was thinking of getting ( still fighting a rough idle and now it seems to miss when cold)
distributor, knock sensor, egr valve, egr solenoid, oil pressure sensor, and a timing light

think im chasing my tail here?
