    Engine stutter

    Hi guys,
    On Monday I did a round trip on the F3 took 4.5 hrs.The first 50km went without a hitch, I was king of the freeway. Then I noticed there was a slight stutter when I put her under a bit of load. So we fought on for an other 50km's. I found a new coil and the old one did look very old, ( $35, ha cheep ! ) and threw that in. No good still the same. Well It may be a lead. Sod it Im only 2000km off a service, so ($50 for a set of leads) still no good ! Grrrrrr. 100km trip back home and she was very sluggish all the way except (Max acceleration) thats fine, plugs are jet black and now in the bin ! Dizzy, AFM, air hoses and throttle potentiometer are all good?

    Anybody had this problem before ?

    Cheers, Coltvas.

    ECU temperature sender: could be open circuit. Should be around 300 ohms hot. 2 wire plug near thermostat.

    Ignition amplifier could be dying. Possible fix here: http://www.aulro.com/afvb/technical-...sch-024-a.html
