I have had my Lambo for about 3 months now. Until recently it had withstood some droppings and misuse. I unscrewed the head to clean it up. The post inside came off with the head. It looks like it was sodered in. I was wondering if any one else has had this happen and what did you do. I just put it back in but get the F1 reading, no resistance. I may try to resoder it and see what happens but wanted to see if anybody else has had this happen first. Thanks.
