All your answers to your faults are the advice i would have also given but one more point regarding your ignition amp as said they are fixed onto the standard airbox side i notice yours has an induction kit and your amp is left hanging out the way albeit plugged in,ideally it needs fixing securely to something solid and some HEATSINK compound applied to the rear of the amp this is how the standard fitment is done,this helps draw away excessive heat build from the amp when being driven as there's no heatsink on yours im guessing then your amp is most likely getting to hot giving you the symptoms your getting  :wink:

It looks like the heatsink is still on it but it's not secured very well...

The plot thickens... Took a trip to the scrappy this morning and picked up a Ignition Amp, new harness for the N75 and replacement oil breather hose plus some engine cover clips, all for £3!!! :grin:
Gonna put them on this afternoon. Also just put some slick50 in the tank to see if that helps.
 On the way home i noticed that my temp gauge is still dropping off to nearly 0 though??? (doesnt seem to do this around town only on main roads) Thinking my thermostat is fooked now. would that cause me problems like im having at the mo??

Been busy with this today, ive changed the wiring on the N75 so that is no longer an issue, fitted the new N75. Replaced the oil breather pipe and mounted the ignition amp back where it belongs. got hold of an air box to butcher and came up with this... works pretty well i think.
.
Problem is, its still not running right. gonna wait now for my cable to turn up so i can plug it into VagCom-lite.
Thought id sussed it but noooo.
Think i may go for a longer run to get the slick50 doing its thing and see what the temp gauge is doing. i had it running for a good 1\2 hr earlier and the temp gauge was sitting at 90 and the fans were kicking in every now and then. would it do that with a faulty thermostat?? Also the air temp from the blowers was red hot but on the way home earlier when the gauge was reading low the air was a fair bit cooler. Do you have to remove the alternator to get to the thermostat. looks a bit of a b*tch to get at.

I've lost track of what you have and haven't done, have you done anything with the MAF? Checked that the throttle body is clean?

I like what you've done with the bottom of the airbox, good solution :afro:
