hello,
thanks for your reply, will try this in the morning.

not a ot of guess work at all, cooling sensor was the only one i changed without testing, for the sake of £16 when i picked up the parts.

The crank sensor was repaced due to keep flagging vss when unplugged and no other code, didnt have acess to scope as modis isnt working.

and o2 sensor was faulty.

so not really alot of guess work at all.

but thanx for your post and will let you no how i got on.

regards
mike
