Happy new year all.
An update on the saga..........
I plan to hook a voltmeter to the MAF output tomorrow, but I am wondering if the IAC valve can/should be adjusted? See this link:

Page 400 on RAVE - Service repair no - 19.22.13 suggests that also.
I cleaned the valve again, checked all the leads looked ok and not resting on bare metal anywhere, lowering the risk of a bad spark. Lucas leads, I have read these are rubbish?
Latest situation is:
Start (instantly no probs everytime), it revs to about 1100 rpm then drops to 700-800 rpm (no apparent missing) then drops to stall (everytime) runs for 5-8 seconds.
Start again, the same, unless I give the gas pedal a little press, then it revs up to 1500-2000 rpm, cycles down to near stall, then again (with no extra pressure on the gas) revs again to 1500-2000 rpm, then back down the whole time it sounds like it is missing. This cycle happens for about 30 seconds or so (or until the missing stops) and I can leave the gas alone and it idles well, albeit slow 500-600 rpm.
Any thoughts most welcome to help me save some funds and while I try to find a local workshop capable........
