hi all well as reward for passing the mot today i fitted a new set of lucas ignition leads and then took the car for a good long run and she seems happier for them,the set i took of had been exposed to lots of engine oil and code date from 2003 so well needed though the car still has a misfire when pulling away and sometimes when changing gear it hesitates a little,then goes off like a rocket.
i have not yet changed the fuel filter and the one fitted looks ancient so maybe that will fix the misfire but i doubt it,properly gapped ngk plugs,new bosch dizzy cap and rotor arm,and now new leads am i missing something and do coils on these cause misfire?any advice welcome,peace
