I know this is a b18c1 motor and this is the type-r forum...but I seem to never get responses in the integra forum. Hopefully posting here is OK.

For about 2 months, my tach needle randomly with skip back and forth around 3-4K rpm. Would this probably be my coil or ignitor? Could it crap out any minute? I don't feel the motor stuttering or bogging at all.

are you using a jdm or cluster or any thing other than your original one that came w/ the car? it might be b/c of the circuit board, (i.e. wrong year)

if its not that.. then its the circuitry.. its gonna crap out...

 

no jdm cluster or anything. stock cluster...just a b18c1 swap in a 92 hatch.

 

i had the same problem with my b16a.. unfortunaly you have a loose bearing somewhere in the distributor you will have to replace the whole assembly

 

yeah.. I had that problem too. You'll have to replace the whole distributor.. well that's what I had to do. I've heard some people say replace the ignitor, but that didn't work for me.

 

OK...I actually have a pretty new housing sitting here. If I transfer my existing coil/igniter to the newer housing...things should technically be fine?

u can try but i think its your internals that are going bad. just take apart the old dist, have the ignitor and coil checked out, and when you reassemble it, use diselectric grease on the connectors (its your best friend).

 

where can i get the internals checked out at?

 

someone told me it could possibly just be my tach crappin out. Any way I can check this out?

 

odds are its the ignitor

 

my tach used to fluctuate and then my car wouldnt start anymore. so i replace the ingnitor and the fluctuation ceased.

 

never heard of the tach itself going out due to fluctuation. but you never know.

you can get your stuff tested at autozone.

 

a way to test out the cluster controls is to take each device you suspect to be faulty and use a voltmeter and a controlled source of 12volts with the appropiate amp/ohm rating.

what will happen is as you decrease the ohm rating the needle will move in the clockwise direction, and likewise if you increase the ohm rating.

be aware the ohm rating should only need to fluxuate about 20 ohm to do this. (do not confuse this with k or m ohm, otherwise bye bye circuit board.)

if it works perfectly fine, then you can assume it is to do with the connection.

my 0.02.
