Ever Since My Ignition Stopped Working Idk My Rpm Goes Crazy Like Goes All The Way To 8000k And Like Rev And Doesnt Let My Car Run Smooth It Goes Like Alot,
When I Am Driving At 80 Iots Going From 6000k 7000k Back And Forward,
Idk Wats Srong With Or Idk Wats The Problem

I Heard That It May Be The Ignition Coil That It Causes This?
Or Maybe Its Because My Ignition Switch Aint Working???
Is There A Fuse That Controls Any Of The Rpm Areas????

The wacking idle could also be due to IACV(Idle Air Control Valve)

My tach would jump to over 8k under heavy acceleration in my Prelude, and I thought it was my gauge. The problem followed me when I swapped that engine into my Accord, so I knew it was something in the distributor. I had already replaced the igniter chip without results, but then I replaced the entire dizzy and the problem went away.

well idk if its cause my ignition switch not working or something
cause yea
i recently changed my ignition module, rotor, cap they aint old say about 1month,

idk maybe the ignititer,?
or igntion coil?

My new igniter still had the jumping tach in the bad distributor, it must have been another sensor in there, or just a short in an old wire. If you can find another dizzy assembly to swap on there, it should help point you in the right direction, even if it doesn't fix things. Engine performance suffers too since the ECU doesn't know what RPM the engine is actually going.
