    First of all i know this has been covered before but what i want to know is if my wiring is cracked is it worth insulating the individual wires or should i wait until i can afford a new loom as its not something i would do myself as im useless at electrics lol so it will cost me alot probably. The car has developed a slight misfire since the cold weather has started the only other thing it could be is the packs but before i think about that i am going to check the wiring as its a weak point on these cars and probably never been done thanks.

    The coil pack loom costs about £20.00 from TPS, I have one ready to install but as with all things, I need the time to do the job. I'm gonna solder in the loom to the exhisting run where it runs under the battery as I don't have the correct tools for taking the pins out from the connectors at the ECU end. That way, only 9 of the remaining wires will require soldering (IIRC) in.

    As a short term fix, insulating the areas where it has cracked can only be a good thing though.

    I saw on another thread that you said they are £20 it might be worth giving it a go myself. The insulation is only intended as a temp fix until i can find the time and money to do it as iv had and got other things to pay out on so once iv got some spare cash i can get it done properly thanks.

    Thanks i was looking at one of your threads about this but i thought you had replaced the loom obviously you haven't lol it sounds like a better plan than replacing it as i can do it myself :)

    No, same loom. I also did this on another one, however used good old insulating tape as opposed to heat shrink. Simple enough to do, and worked like a charm.

    I'm go with that personally, it's much easier than heat shrinking the wires as you have to cut and resolder them to get a good seal.

    Makes sure you get a good quality stuff, not pound shop rubbish as that simply doesn't insulate properly.

    It also doesn't stick well.

    It goes quite brittle when exposed to heat sadly. Also, it's quite thick, and makes it hard to do a tidy job on such small wires....

    Good shout though dude, I thought the same thing but dismissed it due to the above reasons.

    I'm glad you mentioned that Welly, I had considered using it temporarily until I get the loom replaced / soldered-in but I may as well do the job right. Time to start pulling my finger out and sorting my priorities methinks....

    I checked my wiring and found the insulation on the earth wire to the coil packs was broken so i didnt need to strip it all back after all lol but at least i know the wirings ok. Iv re insulated it all though and it seems to have done the trick.
