Right...
1) Done the MAF unplug thing, still did the stall thing. Again, as I engage D from N or P. I'd suggest this is a marginal rev drop, combined with already-low voltage going to the ECU drops by that smidge more, which cuts the ECU out. My 'theory' only.
2 a) Definite appreciable 'rev waver' when engage lots of draining systems.
2 b) Specs of the 'good' volvo battery on a 1-2 mile journey to work and back are...
(no voltage recorded before setting off)
12.85v upon arriving at work
12.53v before setting off
12.87v back at home.
This morning
12.43v after a night sat
12.25v engine running with all the load. (H'lamps, heated seats, fans, heated rear window)
just done a 'cold start'
12.43v before cranking
10.70v on cranking (oh started instant, no issue by the way, but engine was 92
0 as only run ten mins previous)
3) Just a side observation.... the throttle pedal has a fair amount of 'floppy play'
before 'biting' could this in
any way be a contributory factor of this? When I removed the plenum I actually left the cable/adjuster in place, so is
shouldnt have changed position. But could 'tightening this up help matters? Silly thought?
Anyway, not MAF, shame as I have a spare!
