    gday , landrover d2 v8 on lpg impco

    was looking for a wiring diagram and location for the spark plug leads length for each ,and stumbled on this site ,
    I am still looking for one , i bought a set of leads and removed the intake to get the new ones on , rotten thing still backfiring , thought it may be possible that i got one position wrong ? possibly

    D2's will always backfire on LPG unless you set the plug gaps to 0.6mm/0.024". The coil packs are very prone to crossfiring unless you do this. Also make sure the leads aren't tied into a bundle, use spacers or split corrugated tube to keep them separated.

    And if it still backfires you may need replacement coils, I suggest original second hand ones from a petrol-only wreck.
