Well I've been working on getting my Honda Civic running like it should do about six months now. It all started when the rpm guage dropped on the highway. The drifted then SLAMMED into drive as if it went from neutral to drive. I found that my distributor cap terminals looked like battery terimal dust. There wasn't a connect anymore so I replaced it. That lead to more problems. Well the plugs needed checked. After checking and installing new plugs I over tightened one and ripped the threads OFF in the head. SO I PULLED THE HEAD!!! After replacing gaskets, coolant lines, radiator, BELTS, bolts, and ignition coil, now the damn thing idles high at start, levels out, sticks, hesitates on acceleration, AND idles poorly at normal operating temperature. PLEASE! HELP! I've dumped 2k into this already, oh and replaced o2 on the exhaust manifold cuz of codes FM auto zone and O'Reillys. Still same problems!
