My car judders at about 4000rpm in 4th and about 3000rpm in fifth, is this a fuel or ignition problem?
i have looked under the bonnet in the dark and cant see any arking but i can hear a crackle of somehting earthing now and again. im gonna replace the ht leads etc just wondered if anyone else has experienced this???

I think i suggested for you to replace the HTs, dizzy cap and rotor arm at your last service.

actually i think you said they seemed alrite. not that it matters tho

I did do a service recently, and the HTs did look burnt out on someone's motor, sure it was yours, i'll dig out your service sheet.
You'll have to come round for it
