On my 3.9 the closest metric size is 29.

Could also be running rich, check the temp sensor and the MAF if it has one.

Yes i'm looking at doing that on my newly acquired 3.9, it looks disgusting in there. Here's what I'm looking at: camshaft kit with cam, chain, gears, lifters and gaskets. Pushrods and rockers, rocker shafts. You don't need to take the motor out unless you want to replace/grind/bore...

104K? Its hardly run in yet.

I'd do an even more basic check and remove the spark plugs for study. If they look substantially different from each other thats your first warning sign. Otherwise you can google for sites that interpret your spark plug colour. Or post a picture of all 8 here. Keep track of which one came from...

The info I have indicates it should be between 1 and 1.5 volts on a non-lambda engine and 1.8 with lambdas. See how that compares to what you have. OTOH mine was set 3.0 volts (030?) and I haven't changed it since some PO has chipped the ECU (and other mods) and I want to understand wtf is...

The Lucas/Hitachi maf? Does that set the CO trim? Mine does not have an allen but a screw slot behind the tamper proof inside the tube facing towards the windscreen. I thought you had to set that by voltage or is the 30 ohm a base setting?

afm 030? Pardon my ignorance, what does the 030 mean?

Its a Fluke, it auto-ranges. Car is running rich, all sensors test ok except for this oddity. Not tested fuel pressure yet.

I'm testing the throttle pot on a Disco 1, 3.9 engine, 14CUX. Various docs such as Rover 14CUX Hot Wire Mass Flow EFI: Service and Troubleshooting indicate the resistance across the 2 outer wires should be around 5000 ohms. However I measure 10x that much. Should I be worried? Resistance across...
