Somebody said to me the first thing to do when a V8 3.9 EFi is not running
well is to change the temp sensors for the ECU.
When my V8 was running rough (over fuelling) I changed the ECU temp sensor
for about 8 quid and now it runs perfectly.
I measured the resistance of the old one at various engine temperatures
before taking it out and it just gave random readings. It was not even close
to the published specs.

Re: v6 and 7 eighths!

I was kind of hoping this one would be suggested as that was my next
course of action.
