also this may sound strange, but put one wrap of insulation tape around the module and refit to transmitter no more tape, that should be enough ! I was having a few probs...did this sorted

. i know a few people who have had to do this, just tightens the whole think up in the hole thus no movement on the litte conection pins
also as mentioned i run a capacitor in my 10th cars, but not in 8th, but in 8th cars I always run the bigger original recivers, not the micro ones, as for some reason people have had probs with them in rallyx,
