Assisted a friend in solving his no go engine drama. It had all the symptoms of a faulty CAS. On investigating, we found this in the loom... It was spliced between the regular CAS and its plug. It has a genuine Mitsubishi part number... Removing it from the loom and directly plugging in the regular plugg cured the no go, and all runs well now. I've never seen anything like this. ! Its a genuine E38A pre facelift VR4 RS. Cheers Mike
