Intermittent faults are a bitch.

Next time out try going 100% TPS and see if the fault re-occurs.

Shift points are governed by road speed and TPS. Make sure both of those are reading correctly first.

Was interested to see if there are any high capacity v6 sumps anywhere and I found this mob. Not only do they mod v6 sumps to have scrapers and baffles, more oil etc... In the gallery I found a dry sump for ecotec :lol: http://www.asroilpans.com/holden-gallery.html I've got one in the garage, the r...

That is certainly getting up there but then you are fixing all the evils with the dry sump.

Holden V8's have a very shallow valve angle, unlike the Chevy 23° stuff which makes the drain back better but worse valve to bore angle. At the end of the day, I also don't think we are revving our engines high enough for windage to be a huge factor, it gets much worse the higher the RPM. What RPM d...

My low oil pressure was on our L67 VX Commodore. Our street is uphill so you can brake a lot harder without locking up than on a flat surface. I wanted to find the point the tires would loose grip and the ABS would kick in. For the LS motors, I believe it's a design flaw in the block and it's someth...

Came across this relevant video, the guy in it is really goofy but some interesting and surprising results with the oil windage. https://www.youtube.com/watch?v=bk7r0TL0Or4 I've watched a few of his videos, Definitely a interesting kinda guy. I think what that shows is they lack oil/windage control...

That is an interesting point.

Probably need to measure EGT too to get a better idea of what is happening in the cylinder. The other thing that comes to mind is moisture changing the burn of the fuel. It's been a long time since I've looked at it but they used water injector on aircraft and it changed the fuel burn characteristic...

As you say, moisture in the air is supposed to be a bad thing but then why does water injection increase power? I remember my old 308 was really happy on cold mornings, especially when there was a bit of fog about, you could hear it in the exhaust note. Maybe it's the way you have it tuned? Factory ...
