going to have to, i wanted to diagnose the problem but the obd is different and i purchased an adapter for the round 38 pin to 16 pin but that isn't working. need to get into it a bit more. mine doesn't have a distributor like yours, the leads go into two seperate rails. certainly going to replace the plugs and leads though as two are black two are good and one of the four leads is different. thanks.@@zabzproject1416
