Question turboII problem help appreciated

Well after searching the forums I couldnt find a thread talkin about the same problem I have so heres the problem:

1987 turboII (mods:intake, emmisions removed, 8mm spark cables, exhaust)

-when i turn on the car (cold motor) it turns on with one or a few tries but idle doesnt go above 1k rpms and the idle is slightly erratic (bouncy "brap brap brap" idle that resembles a bridgeported rotary sorta).
-once its a warmed up i need to hold gas to idle
-when motor is warm/hot i either have to hold down the gas pedal all the way or take off the egi comp fuse from the motor crank it up for 10 sec and then try again (like if it was flooded) but after these methods it still takes various attempts.

-after a couple days its gotten worse and power loss is noticed and the car bogs when i move from a stop.

what can the problem be? all help is greatly appreciated, im thinking about taking it to mazdatrix or rotary shack since its the closest rotary mechs from where i live even thought theyre pricey. but if somebody can reccomend somebody else thats cool too (i live near LAX). thanks

i bought a fuel pump, and some months back i put oil stabilizer in my fuel tank thinking it was pre-mix (thick substance) so im thinking maybe its really clogged up now but eaither way i havent replaced the fuel pump for a couple years. but could that be the problem?

Have you checked your spark plugs??? Fouled plugs make the car sound like it's running on one rotor (at least that's what happened to mine).

check your TPS.

BUY A VOLTMETER and have fresh batteries.

do this:

if you check it and you see it off of the 1K ohm adjust it. make sure the car is FULLY warmed up.

good luck and don't freak out just yet.
