mantaboy89 Posted August 3, 2013 Share Posted August 3, 2013 I've got a 20seh fitted in my manta. Believe it's using the 1.8 dizzy setup. Got a fault with it and gives me a nasty misfire under load. Rev counter needle bounces around when the misfire starts? Just fitted it with a new ignition coil and still the same anyone got any ideas, would be grateful for the help?

dynamytedan Posted August 6, 2013 Share Posted August 6, 2013 the ht lead is leaking near the coil and jumping down the rev counter wire . try looking in the dark you may see it arc out . Quote Link to comment Share on other sites More sharing options...
mantaboy89 Posted August 6, 2013 Author Share Posted August 6, 2013 Have already looked in the dark but the fault only happens under load. But what you have said sounds like it could be it. Will try a new set of ht leads. I thought it could have possibly been the ignition module? Quote Link to comment Share on other sites More sharing options...
