1993 Accord (bone stock) .. Starting having this severe spotering about week and a half now, at any speed but mostly on the highway and making it dangerous to drive. While going around 60 mph the rev meter wil jump back and forth from 3000 to 5000 o more but the car wont change, then sudenly it will jump back and forth from 3000 to O!! and thats when it spoters realy bad ... So far I chaged the distributor, cap and rotor, sparkplug and wires plus coil but problem still remains. Planing on replacing the fuel filter tomorow and if it continues then Im thinking maybe the ecu...... any help? Thx

 

remove the dist cap and look at the igniter see if its a black oki or brown nec.
