Bouncing Tech Needle.

[goldwing1800]

I have A 1990 Civic. The tech seems to have a intermittent problem of going on and off, when I het a bump. Anyone else have this problem, and how did you fix it?

Could be the dizzy. When I had that problem I pulled it and the blue wire was corroded. the tack works fine with the new one (had to replace it for other reasons)

yea, i'm almost certain it's related to the distributor. atleast i know that when my ignition coil was going, the tach would go crazy and start bouncing as if it was getting random surges of power and whatnot whenever i accelerated really quickly or hit a bump.

Ignitor and or coil.

Soon your car will stop working. Mine did that about 3 months ago, it worked for about a week or two and then it just broke. So I replaced the ignitor and the coil.
