I have the 94 sohc v-tec motor in my 94 civic. My problem is that when my car idles it goes from idle @700 rpm to about 1500 rpm by itself. It just goe up and down up and down like there is a rythmn to it. HELP ME!!!!!!!!!
the problem is probaly a air pocket in your coolant system
as u say the car idle just goes up and down
to fix the problem just take off the rad cap [cold] and let the engine run till the rad fan turns on.
this sould solve the problem if it doesn't then let me know
