Check the wire to the AFM. Either that or the AFM is goosed (which happens if you fart loudly near a Z20LET aparently). :)

Check the fuel valve connections - have you disturbed the piping that goes and returns from the carbon filter? if one is unclipped (think that they have bright green connectors?) - this could be your problem, as they are next to your airbox.
If it's your AFM - then you'll be in emergency mode from the sounds of it - which limits your revs and speed to about 60mph? usually you would have a light on though by this point it it's this.

Should do, although if you have disturbed anything 'important' then an electrical sensor would pick it up.
I'm a bit confused - do you have a light up on the dash or not?
I know this seems a bit of a thread hi jack situation but...
Scotty mentioned the carbon filter, has anybody had any problems with this thing ticking loudly? Mine does, sounds like a tappet noise. Also, is there a fix for this?

is it coming from the lefthand side (on the pic) cos i have a slight ticking noise and vauxhall say its normal
Check the actuator rod on the turbo mate, I have heard, and seen of a couple of cars where the 6mm nut has come off the wastegate arm, resulting in no boost, right at the front of the engine, just behind the radiator, to the right hand side of the manifold cover.
HTH:wink:
But slinky, it's so chuffing loud! I can tell it's that cause if I pinch the tube up (for a very short time) it stops. Ah well, I'll just keep turning the stereo up then!
