Im suprised if it sounds as bad as you say there is no engine light on  :-/

not a single light comes on at all. it has no power to even move when it does it.  You have to rev it up hard to clear it out.

Does the engine light or the one with the spanner come on when the ignition is turned on or have the bulbs been removed to hide something .

a spanner light came on about 6 weeks ago.  i pulled over and turned off the engine.  waited a while and turned it back on and it never came on again

I had something similar happened to mine a while back ... im sure they changed the coil pack on it if i remember correctly .... someone with more expertise will be able to give you more ideas to check first though  :y

Possibly a stupid question, does it have a Carbon Particulate Filter???  May need changing or clearing if it does...

joined the AA today and had a word with him.  he said he was called out to one the same and the light coming on was due to contaminated fuel.  apparently alot of it going round at the moment.
I have bought some new plugs today and my son in law has cleaned out the coil pack a bit.  See how that goes ::)
I love this car but its proving to be a right pain at the moment ::)
What is a carbon particulate filter and how will i know if it has one :-[
Sorry about this but not that knowledgable of cars :-[
