my car dies when i trie to accelerate!!!

obviously by the title this is not good for any zed! but i have kinda identified the problem, there are wiring looms and wires with connecters at the back of the engine bay on top, if you look on your car you will see(il upload pics tmrw) but anyway when i try to accelerate hard or open the taps a bit the car just jumps then dies! i roll to a stop and sometimes i can restart it but sometimes i have to leave it overnight and it will start in the morning! (wierd) but anyway when i move these wires and jiggle them around the idle sound and speed changes, and when the car doesnt start completly il get sombody to fiddle with those wires while i turn the ignition and it will usually start! so i opened up the loom to see if the wires are damaged and a few are! not completly burnt through but a bit damaged, and i was wondering if these wires go to the spark plugs or somthing, cuz its just getting no spark, also now when i first turn it on i have to keep the revs at 1000 or it will die but if anyone has any ideas please help!!!!! thanks!!

    The ptu sends the spark to the plugs, might be part of the ptu loom, also check the connectors on the ptu, its at the front of the engine just below the intake pipe, if its a series 1 ptu it will have fins on it.

    Ptu as Groover states, also sounds like your( TPS )throttle position sensor is duff.

    Check out the connections to the MAF (under nose cone)

    These engines are prone to react badly to the green corrosion on connectors.

    Worth checking all that you can and clean em up.
