tach doesnt work....cant go past certain rpm
 
well im still fiddling with the car and i replaced the ground bolt to the firewall, checked the bolt to the head and they are good. However, the tach doesnt work at all, and just to see something, I tried to ride out first gear to about 45mph. Well at about 30-35 mph, the car acted like it was bouncing off a rev limiter. Last time this happened to me, I tightened up the ground bolt to the firewall and everything was fine. need help asap.....vehicle inspection runs out this month and dont have $/time/patience to mess with this thing all winter.

have you checked the white wire going from the tachometer to the ignition coil?
