I just installed new timing belt and skunk2 cams and some problem occured.

when i hit 4K rpm or above, the rpm needle jump up and down like crazy. can you guys tell me what is going on with my motor?

 

Have the same problem, but i had it without changing anything, just dit a swap from D16Z6 to B16A2 and didn't know the condition of the new engine. I asked around with some people and they say, distributor cap, or the ignition coil, or even the ignition wires. i'm gonna test changing the distributor cap and rotor first, if that doesn't work im gonna borrow some ignition wires to test, if that fails i'll take the ignition coil from my old d16z6 (same part as the b16a2).

 

check your ignitor

 

it's what mmuller said. the ICM/ignitor sends the signal to the tach... when it's jacked up. your tach goes: WEEEEEEEEEE.

it can also be the speed sensor on your tranny...

When my clip on my VSS came off the speedo didn't work

When the ignitor went bad what he is describing happened. Check that ignitor or or replace it

 

when bad ignitor, tach will act funny or not work.
when vss is bad, as sayd above, speedo will mess up

 

try to check ur ign. coil

 

Had this problem and it was the ignitor.

 

thanks for all the help guys. i already check the ignitor and sparklug wires, they all in good condition.

when the engine getting hot after 50 minutes of driving...then the problem occurs as follow:

rpm needle jumping incorrectly after 4k
HP and TQ lost dramatically

Is it possible cause by advance timing too much?

 

When mine started doing it, I took the ignitor out and couldn't find anything wrong w/ it either, so I drove around and then I had to change the dizzy because the seal was jacked up... and when I r2'ed the dizzy, problem went away.

yes, try swapping ignitors, and see what happens

 

I"m having the same problem now too. I have a spare b7 dizzy laying around, can I used the d series ignitors in a b series dizzy? Non-vtec b7 to vtec gsr.

I use the Igniter and Ignition coil from my old D16Z6 distributor to my B16A2.
