my tach in my 88 crx si tends to bounce when I'm reving, anybody know why? is it some lose wire or is it the gauge? what do i need to do to fix it? Thanks all

usually when you rev your engine, the tach goes up and then down

imported_crx168

yes, if it's good, it gives me the reading too..but I could be reving at 2000rpm and the needle would be bouncing at 8000rpm...not good at all eh?

check yer grounds on the car..especially in the engine bay..

I second the check grounds ... I'd also say check tach wire continuity as well

dizzy , cap rotor, igniteter

Had the exact same prob and this solved it

Obviously it just started.......so go with the recommended solutions and I have a rotor and distributor cap for the 88-91 civic crx.....brand new....PM me if you want to buy them as I now have a ZC motor so I don't need it.

I've been told that its the dizzy starting to go.
I have the same problem (sometimes) when i rev high.

Thanks guys. I am not sure if mine is the same problem as yours. put it this way, while i idle, my tach is boucing at 7-8000rpm already.

<br> so the problem isn't the same as yours where yours would only bounce when you gas to 3-4000rpm. mine just bounces with or without gas. could it be a sensor or anything?

Swap out the cluster..

If it doesn't go away try the dizzy next.

Original motor?

imported_crx168

yes orig motor

Thanks Guys, I fixed it. It was a ground problem
