My HSGR Lives / Dies / Lives / Dies again and again

And as I said it starts and runs perfectly ATM and has done since November.
So I could swap parts and still have the problem

I'm a little confused- it runs perfectly but you still have a problem?

Yes

if you see the first post in this thread was Nov 2010 and run through the posts you will understand what is happening

The problem has occurred intermittently and I have no idea when or if it even will happen again

I just have to drive and keep my fingers crossed.

Hence the idea to clean up all of the connectors in the engine control system
which still will not tell me if I have found the problem (even if it works!) unless I find a burnt contact or loose wire.

Don't you just hate it?

It may even be OK now and the ECU just had to catch up with the replacement of the sensors? but I don't think so
I wonder if the ECU has a backup battery? I have to think of these things.

BTW coils were replaced early in the saga

Maybe

But only maybe

Found cover of wiring loom to engine control relay fretting on a sharp point behind the left hand speaker in the dash
There was a bit of plastic wrapping stuck to the sharpish edge, and the covering of the loom was a bit shredded
Couldn't actually see the wires due to space but this would be a good point (hehe) for an intermittent earth fault
Covered offending bit with insulating tape.

It is probably drawing a long bow here but I haven't had any trouble since early December last year

Maybe I can now declare it fixed???

Buggerit anyway I'm going to Adelaide this weekend!!
