I got a b16 in my 94 hb vx and my tach jumps up and down all crazy after 4K rpm. Does anyone knows why and how can I fixed that. All the plugs are plugged in right and the car drives fine. Thanks for you help

check the ground strap near your tranny...

I'll go and check on that right now. thanks

boostn5Ghaba

the ground is there and in good condition. thanks though

I'd check the igniter in the distributor. I believe it is responsible for tachometer functioning, and the signs of a failing igniter include erroneous tachometer output.

thanks raeneshadow, I was thinking i had to do something with the distributer too. I though it might be the cap, but I'll check both.

do u have an ignition box??? my friend had this prob when his box went bad it caused his tach to jump. he removed the box and the tach worked.

boostn5Ghaba

No I don't have an ignition box. I was going to install one when I get my turbo but right now it's stock. I think it's the ignition coil in the distributor. thanks for you help though

usually this is caused by loose connections on your igniter- pull off each wire and tighten the ends with pliers.

Have you solved it yet? I just had this happen to me last night. I to thought it was the connections on the igniter. Everything was tight though. I replaced it and now my car is back to normal! I hope this helps!

I'm going to check on the connections tonight, but I'm in the process of looking for a new distributor just in case. Can I just replace the ignitor?

fixhondas

yes- you can replace the igniter itself
