my car has been running a bit crapy latley and it slowly getiing worse. I noticed that when i was cecking stuff out that there was a blue spark coming from the negitive prong on the coil to the lead that goes to the dizzy itself. has anyone heard of this?? ahs this happened to anyone else???

You may find the spark is jumping FROM the coil lead TO the negative prong.
Check the resistance of the coil lead, (1000 Ohms/inch I think), make sure thers no cracks or perishing around the rubber boot for the coil lead, and that the button in the centre of the dizzy cap is touching the top of the rotor.
Also clean the outside of the coil and all the contacts really well,

Yes, this is a common failure mode of a coil.

Sometimes it indicates a misfire in the engine, as the spark will normally jump the spark plug gap instead of at the coil.

I've checked all the leads and they seem to be in good order, i even bought a brand new coil but it seems to be still doing the same thing, espeiacally first thing in the morning. if i press the accelerater pedal just a litlle it works but if i accelerater all the way it coughs and splutters and strugles. could there be any other problems that comes to mind?

crook lead
do resistence checks on all leads
