Hi if your the Alex mentioned to me in my thread by VDT as follows, then please let me know, maybe I need of some bits. Thanks Dez.

Just read that your capable of doing suspension rebuilds.Right then.......your capable of doing this also to fix your misfire problems. Your wiring for the coils is most likely cracked and arcing all over the place. Take the lid of and show us a close up pic,only 3 x allen bolts. If it's cracked, you need a new loom. So you might as well approach Alex on here (error404) and S2 forum for one of his new looms and then buy the modern coils he recommends.All this is very easy to do and needs no specialist knowledge. This should be your first port of call.
