Changed the distributor cap and rotor arm

What a nasty little job that was (fractured my wrist last week so a bit of a challenge).
Admittedly the cap i took off was shocking, but that hasnt sorted my problem unfortunately.
Tried swapping out the iac controller too, but that isnt it.
Rechecked hoses for holes and splits - all ok.

I cant get over that it starts, ticks over for 10-15 secs, then drops the revs then brings them up to 1.5-2k revs then down again! I got it do that on its own 8 times yesterday while I stood and watched.

Grateful for any thoughts .....

regards
piers
