Right - removed MAF and gave it a clean. That said - it seems the only thing to clean is a small diode that's bent back on itself and held with contacts. Anyway, cleaned it with lint free bud and non residue pcb cleaner. Put it back in and TBH no noticeable differnce - possibly felt a bit lighter on the throttle at 1500 - 2000 rpm.
So, unplugged the MAF and a slight improvement when pulling away and certainly felt livelier through 1500-3000 but no significant difference to the juddering when pulling away.
One worry was the engine management light came on and stayed on even withe the MAF plugged back in - was seriously worried I'd knackered something. Anyway, after a stop/start journey home via shps and chippy it eventually went off
So, the conclusion. I dont think the MAF is causing the juddering, that said given the small improvement and the fact that she has 120k on the clock and Ive done 30+ k of that and the MAF has never been changed I've decided to change it as it cant hurt
The juddering, BTW, seems to be rev related, in so far as if I increase the revs and balance that against the clutch biting I can ususally control it, it's just not that smooth. I'm always concious that if I had to do a quick get away I'd probably stall her. I'm wondering if it's more clutch related but given she has self adjusting clutch I wont be venturing down that road.
Last question - which is not related to the MAF now, so I'll open a new thread - but how easy is it to drain the clutch hydraulics - procedure??
