Ive got same problem (also 135 but not as important as 74). Can't find any other posts to help. If I find anything I'll pass it on.

To do: Replace brake discs and pads; adjust already replaced shoes; check for leaks in oil cooler, cambelt area, crank seals, sump, dipstick; replace osf door; replace a tyre; clean, MOT.

can hear TB now, Maf failure very rare etc.

Often thrown by crank sensor issues?

Check wiring to and from? Personally not sure what the voltage high(or low) means while on the subject...Anyone?
 
Swap for a known good one if all else fails?

But you probably know all this tbh.

Try the plug...does it clip into place like it should??

I swapped the MAF over on mine...the plug clipped into place unlike on the old unit...think the old unit itself is ok but not had a chance to test it yet...
