car has started missfiring and i dont really no what else to look for its not really a missfire just every now and then it pops and bangs a bit i have changed plugs leads etc thought it could be the hall effect sensor but if it was it would be constant so any help please guys

 

A fuse gettin hot is on it's knees.

A 30a fuse has a blow rating of 60a and is rated at a continuos 30a. If you ask it to draw more than 30a it will start to get hot. Obviously the more current you draw through it, the hotter it will get and it will get hotter, faster.

 

sounds like the distributor is on its way out as same thing happend on mine untill it packed up then i changed it and was fine

 

I can't help but notice the title says fuse hot but you didn't mention anything about what fuse is getting hot and why you think its related?

Hall sensors are all too prone on RST's, but usually play up on boost and make the car back fire quite spectacularly (i've scared quite a few pedestrians )
