Hello all, I'm `Pete, based east Sussex, Great thread, brief intro: Oz based Lc 120 GX (4.2 Petrol) for 5 years, 120 2005 lc5 d4d UK based since 2015, great vehicle, except....... thinking I've got the SCV issue you chaps are discussing , thought it was immobiliser, or key-fob , but resetting (drop batt - leads) works, and at idle she cuts out, did not know the SCV replacement was a recall item !!! found that out on this thread, - muchos gracias!! did a tank clean by my mech (who is superb btw) and he found. this on the fuel pickup strainer, tank actually clean, but strainer & fuel system needed a flush, thinking the SCV would have ingested this prior to clean, and any upstream/downstream fuel pressure sensors would pickup poor SCV operation and force engine cut-off at low rpm, no issue with driving it, but cuts out as per other examples on this. thread.
`love the vehicle, so I'll get the SCV replaced asap, and then move on to the ECU or electrics, (which scares me more than any mechanical fix).
I have the Ellery manual from Oz and whilst its a good source of knowledge , it is perhaps , the worst indexed maint manual I have ever come across!!
