The tach in my 93 civic isnt reading right. When i hit vtec the needle bounces all over the damn place so i have no idea when to shift out. I have no clue what it could be. Any one have any clue as to what could be causing this? BTW its stock sohc with n1 exhaust and magnecore plug wires.

 

If you have a friend local with a 92-95 civic, try swapping the cluster out to see if that's the problem first.

 

ok i tried that and it still does the same exact thing

 

Does your speedo go crazy too? If so you might want to look into getting a new dist.

Or if you can swap it out and see if that fixes it, if it does you know what the problem is.

 

no the speedo doesnt go crazy just the tach. I will try the distributor thing and see if that works. thanks for the help

 

check you grounds too, but dizzy is a good possibility.

x2. Dizzy seems to be most peoples problem when this occurs.

 

ok something is wierd about this. I changed the distributor, and it still did it.I checked all the grounds and they seem to be fine. This morning i changed the oil and then went to "test" it out. The tach swept all the way to 7 grand with no skips or jumps or anything. Wierd

 

make sure the neg. is on tight on your battery.

 

wierrrrrrd

 

Maybe a friend is playing a joke on you? ...I'm clueless now.

 

Mine does the same thing. Motor runs fine. Apexi displays right rpm. Tach in cluster bounces all over the place.

 

that is most likely caused by a bad ground some where in the system... u can check system with a scanner if u knoiw what ur doing
