My 98 civic LX (auto) as started to idle high to low in neutral or drive, the speedometer is erratic and lights are the same. The problem started with the engine light coming on then 10 secs after the speedo went crazy and the car was idling real funny. We drove it home asap and just got worse.

I replaced the computer with no luck. Does anyoneknow of this problem and what can be done.
Thanks
Vince
