I've been getting a wierd hesitation when i'm at about 2800 to about 3000 rpm. I've only noticed it in third gear so far. My car is an 89 crx with sohc zc and stock si ecu. If it's only at a certain rpm range like it is, does this usually mean it is ECU related? Any help would be great!

 

change your spark plugs and wires and move the dizzy to adv it a little more and it should fix for problem
