My 1999 Honda Accord Automatic 4 Cyl has begun to miss or drop a beat at idle. It idles fine and then misses a hit or 2 and then will idle fine again but missing at anytime continually. It also upon reaccelarating may miss/lope and then continue fine. I checked the spark plugs and they showed normal wear, put on new PCV, checked air filter, and visual check of hoses. Car is needed so any help would be appreciated.
