Klze Idle Problem!?

alright well to make a long story short i dropped a KLZE in my 94 probe gt....after all the bullshyt i went thru to get this baby in its finally almost there....my problem is when it starts up it will rev high and then want to die unless i keep hitting the gas pedal....anyway i have one mod done to my distributor the HEI Ignitor mod...if anyone knows anything bout this....could this be causing it to rev high or would anyone more,less say its a vaccume leak somewhere in the engine....i know i have one vaccume line loose from the EGR solenoids...but any help would be appreciated..thanks
