Ok... big thanks to rockerz who came down to see the car! new spark plugs and a few tweeks here and there, but yet still same problem. Been told it may be the ECU :'( which leaves the dilemma of breaking it or sticking a new lump in..
that has mind boggeld me mate, i would'nt stick a new engine in as it will cost you a fair wack to get it through an mot as it stands now
your best option is to get the wheels sold and steering wheel and there will be some chav some where who will buy the body kit.
on my old valver i paid £400 for it and spent near enough £3k getting it back to good condition and at that it was not perfect.
it went through 1 jb3 gearbox and a jc5 wiliams box ended paying out for a 172 box in the end on top of a new clutch, driveshafts,
wishbones ,steering rack, new track rod ends,full front and rear brake setups and rear calipers, full service,starter motor,aux belt ,welding,getting the emissions right etc...etc
alot of the listed was just to get an mot on it, thats before i bought coilovers and new tyres and things.
it would have cost a lot more but i done it all apart from the welding so i saved a fortune on labour costs. trust me cut your losses mate and try and get the money back you have layed out so far.
heres a few pics of my old valver wish i had kept hold of it now
