i have a 1st gen integra ls and when i bought it it had some front end damage and a blown 65amp underhood fuse now while everything still drives great all electronics seem to be working my tach "twitches" veeeryy little when idling around 800-850 but really bad when im driving ill be cruising at 70mph and my tach will be bouncing between 5k to 8k i have not replaced the fuse with another fuse yet i just have it bridged with a wire but any ideas? also if anyone knows where i can get a cheap LH fender and headlight assy and front bumper assy you would save me a lot of time thanks :)

Find out where the ground is and clean the ground wire. If not its either the wire from your icm or the icm is going bad sending a bad signal

check your ground, it will be around the distributor, on 2nd and 3rd gen integras its on the thermostat housing. there should be around 3 grounds in your engine bay tighten and clean them all i had the exact same problem, if that doesnt work try another distributor modulator or another dizzy. mine was so bad my car would die out, that ground controls your dizzy and injectors i think
