Keep getting a really bad misfire when it rains, no water is getting into my engine bay at all. I have changed the plugs, dizzy cap and rotar arm, added extra earths to the coil and ignitor but no luck.
Any suggestions
btw - im still using the same blitz ignition leads that came with the car when I got it 10 years ago, the still look like new and cant see and rips/cuts/tears in them and they still have a tight seal, I was told they are supposed to last a lifetime?
Well who is to say .. how long a lifetime is??? But an easy way to see if the wires are leaking, is to fire the motor up at night and look at them. If they are really bad ... they will light up like a Christmas tree at night!
Short of that the Vaseline couldn't hurt but I'd also unhook everything you can, on the ignition and spray it with WD 40, as it displaces moisture!
