Ok, I think I found the problem with my car, I believe it's a vacuum leak or maybe a problem with the vacuum advance mechanism. I will check thoes out tomorrow and get back on that. But my problem at the moment is my tach, it likes to do a little dance. At idle it is just fine but once you hit the road it will be anywhere from 0 to 8000rpm which Hell I have no problem with I never use it to shift but when I go to sell my car it might be a good idea to have that working. I have been checking the manual and it says nothing about the Tach. I am just wondering is the tach done by a cable, if so where is it and how do I fix this problem. Or is the tach run by vacuum again how do I fix or is it digital?? Ohh yeah car is an '88 Civic SE.

I think its controlled by a tach sensor on the distributor...
not 100% sure..

The speedometer is run by cable.

Yeah, so check for loose connections on the distributor clips..

I'm not sure what the color is for the tach wire. You'd have to get a pin layout for the dizzy... Most likely it's just a loose connection otherwise the car would be acting up.

Is the ecu showing any codes? The ecu panel is under the passenger foot carpet.. a metal plate with an led in the middle. Turn the key to ignition and see the blinks.. long blink = 10s, short =1s. count them.

the tach signal wire is generally blue or green

posible u have a problem with ur ign. module or a loose distributor rotor. the tach signal is at the side of the module or igniter with a blue wire


good luck
