f22a1 coil and tach.. HELP PLEASE!!!

[bigbadnothing85]

ugh... im kinda newish to hondas but not really... 93 accord lx... usual honda... cost 250 and im doin it up for the lil lady... ive been gimpin around with the bouncy tach for a couple weeks... it read fine up to about 3.5-4 grand... now it bounces at all rpms... the coil has no aparent signs of damage... ive been looking into it and the coil and ground strap are the most likely culprits i think... my main ground on the front of the block is frayed up... is there any possibility that the ground could be the issue??? any help will be GREATLY APPRECIATED... i need the car runnin so i can make my 75 mile drive home from work...

oh its an external coil if that helps

[bigbadnothing85]

ok... nothing yet.... how about this.... i have a 90lx with an internal coil... would i be able to use that distributor on the 93? if not how about the ignitor brain?

if you have internal coil then yeah i would say it would be the coil taking a crap. But since its external coil, they rarely crap out. Its most likely the ignitor unit causing all the issues because that's still inside the dizzy and takes the brunt of the heat and abuse.

[bigbadnothing85]

will the igniter from the internal work on the external? or can i just swap the whole dizzy?

Ignition coil are different from internal and external.

Igniter are same as internal and external.

I would also check your alternator belt. This happened to my friend a year ago.
He had a hard time diagnosing the problem and it turned out to be that. Also , I would redo your ground points.

awsome news on the igniter man... you just saved me... im changin that little bugger when and if i make it home lol! i kinda figured on the belt... i already bought a new one last night becasue it started squealin like a banshee. thats awsome the igniter is the same!!!! thank you so much for the intel my friend

would this be the problem in my 91 dx. i drove it this mawning and the rpm tach bounced from 3 to 4x rpm? i changed my rotor button and dizzy cap cause my car doesn't crank on 1st turn over when motor is warmed. cranks fine in the mawning. so could this be my prob?

[bigbadnothing85]

it's a very good possibility... i've been on ALOT of honda sites and even called a few local speed shops... they all say to check the main ground strap and the igniter in the dizz goes bad... i swapped out mine with my other dizz and it works perfect... the car runs better and everything.....
