I think i might have an ignition coil problem in my h22. I used an ignition coil from a 98 civic. My car's tachometer has mini seizures once in awhile. Sometimes there would be a sudden power loss, but it was okay until a day or two ago. Now if i drive it, the tach goes crazy and my car constantly stalls??? Does this sound like an ecu, wire, or ignition coil problem?
