Vacuum fluctuating + tickover problems

[madmax_926]

hi all,

recently removed the air con pipes and disconected the plugs at the top of the engine where they connect to the intake manifold.

i capped the pipes on intake mani.

anyway what im noticing is my vacuum reading on the greddy profec is fluctuatiing quite a bit and occasionally the car will bring it self to 1100rpm tick over for a couple minuites and then drop back to the 900rpm tickover.

the above has only happened since removing the air con plugs and removing and capping the pipes^^^^^^^^^^^^^^^

ok the other thing is when my is up to operating temps and then turned off to say go into the shops ill come back out start it and the revs will go down to 700 rpm tickover almost just above stalling from here i have to rev the car for a minuit or 2 and it manages to sort itself out again.

what do you reckon?
