Distributor pickup coil,.. HELP
94 4runner v6 throwing a code 12 (rpm signal)... ignition coil tested out good, put in a new ignitor. no change. still takes about 2-3 keyturns till it fires up. loss of power, and misfiring. pulled the dist. cap and rotor off to check the air gap between the signal rotor and pickup coil... fsm states it needs to be from .008 to .016 inch feeler guage. smallest guage i got is .010 which doesnt fit. the tooth of the rotor and pickup coil are very close together and judging by the way it looks, i dont think an .008 would fit either. can the signal rotor be adjusted or is my distributor going south?

pickup coil is in the distributor. remove the dist. cap and rotor. look at pic 2 where the tooth of the rotor is lined up with another metal piece. that metal piece mounted on the black part is the pickup coil... there should be a gap between that and the rotor tooth. from what i've read, if its not within specs then it could cause your vehicle to sputter at low rpms.

UPDATE.. so i picked up a used distributor for $65 and compared it to mines... when i removed mine from the vehicle and turned the rotor by hand it had a clicking like sound. the teeth was making slight contact with the pickup coil. the used one that i just got does indeed have and air gap between it and turn freely by hand without contact. installed it and my engine fired up as normal. however after pulling the efi relay im still getting a code12.. gonna try again tomorrow and disconnect the battery to see if the code is gone. sounds good so far though.
