little tach problem

[Jr_toy]

dont know if its a emergency but when i race sometimes my tach starts jumping all over the place. i've replaced my cps and i know thats runs the tach. just wondering if others peoples does this?

thanks.

actually the CID (cam sensor), is partial to the tach signal too...i know i had to replace my CID to get the tach going again...and to let the car start.

now my CPS is in the crapper (about 3 months after the cid)...no tach problems, just hard to start and stalling.
