OK....
and I believe it to be fixed!!
Which one is the smoking gun, I'm not sure, but just glad it's back....
I now have a good baseline for Ken's EZK chip on its way to the UK!
- new battery earth strap
- new Lowe ISV
- fuel pressures checked
- new Speed Reference sensor
- new intake manifold gaskets
- engine earthing points cleaned
- all other intake electrical connections checked and cleaned
- vacuum lines checked
- MAF checked
