EA82T '85 - ignition cut out jolt !

[jono]

Hmm, been getting the odd, random jolt as I zip along, light load once, just off boost for another jolt. It is ignition cut out and is whole of engine, momentary cut out and back to happy again. It is gonna catch me out one day and really upset the traffic around me. Wondering if it is characteristic of the 4 pin ignition modules in the EA82T first series with 3 plug ECU, flapper AFM systems??

 

Sort of a bit like when I had the std 2 pin modules die in my EA81's - a precursor warning before completely lets one down.

 

These 4 pin modules are nearly $1000 from Subaru ex-Japan or $300 Rockauto. A breakdown tow job is similar to Rocks pricing and stil doesn't make engine spark again..

Anyone had similar experience with these early systems and have an outcome ?

 

My leads are maybe 60,000km old, genuine $100 coil about the same age. Non genuine made in China did not last more than 12 months. May be time to check fuse links, relay swap, battery terminals and earths ??
