well i bought my new car, a 98 honda civic hb and about three months ago the check engine light came on and my head lights started flashin, everything was, and the speedometer went haywire. My dad checked the alternator and it was bad, got a new one, put it on......still flashing, so check it it was good, put it back on and wiggled wires. It was fixed and fine up until two weeks ago. happening again, and it'll stop flashin if i'm turnin over quite abit rpms, most of the time....i have asked so many people, had it hooked up to get the codes, problems: o2 sensors and the speedometer was unplugged so it was "bad"........can't figure it out, any ideas whats going on???
