Not running properly
Periods of wet weather are making my rocco im possible to drive. The engine turns over but wont start. Got out the wd40 and gave the leads and everything around it a good spray. Didnt make any difference at all. Eventually got it started and set off but it was misfiring if the accelrator was pressed sharply. Stopped at some lights and it cut out and wouldnt start again. Tried starting it and it produced a massive cloud of smoke from the exhaust as well as a loud back fire. Managed to get it started and get home and then it cut out again. When the weather is dry it works fine. Any ideas?
Re: Not running properly
Sounds ignition-related to me.
Usual things:
Check for a decent spark from coil to distributor, also from distributor to plugs (all of them in turn - it's possible one lead is causing this).
Check plugs for condition.
Check distributor cap for cracks, tracking or damage.
Check rotor arm for excessive corrosion or damage.
It could also be timing, but I doubt this unless you've been playing around with the position of the distributor.
*edit*
Could also be symptomatic of an over-rich air/fuel mixture, but again, if you've not changed it, it's unlikely.

check the dizzy cap for dampness, cracks and general condition.
and stop spraying wd40 on your leads! it will rot the rubber and make them fail much faster and just make lots of shit stick to the oil. drives me up the wall. wouldn't be so bad if it actually fixed a problem, but 99% of the time it doesn't. [/caffine fuelled rant]
when it gets dark to night, fire it up and open the bonnet (find a nice dark place with no street lights shining onto the enginey bits) look closely at the leads and check for any tiny blue flickers on them - this would indicate a problem with the leads. if it won't start, get someone to turn the key while you look.
