4x4 saph misfire
hi all, second post on this now. my 1992 4x4 saph has a high tension misfire.
if you slowly accelerate through boost it is fine. but if you boot it through boost it backfires and misfires. spec, standard green top engine with scorpion exhaust.
so far it have checked 3 blocks on wiring loom, no corrosion.
tried 2 sets of plugs with various gaps. 071c at 1.05, .9, .65, .6
when i tried the 071c it made the car run rough as a badgers arse.
not sure type of plugs that where already in the car when i bought it(going to try smaller gap) on these plugs
has had new rotor arm and dizzy cap.
waiting on new ht leads.
In the history with the car there has been work carried out for a high tension misfire resulting from interference from ignition. parts of ignition where changed because of this.
any other possibilities will be considered and appreciated
cheers in advance
