[urq] Engine Cool-down noises / Excesive Fuel Consumption

The ticking is quite normal with new EM, and its from the contraction of 
different materials. It will stop when the contraction - expansion path 
is established.
About consumption, if you have clean air filter, and the fuel reading 
potentiometer adjustment hasn't been altered, and you tried it with CSI 
disconnected, and the WUR is working correctly, and the enrichment 
switch isn't connected all the time, and if the enrichment solenoid 
comes in at correct time, (eh, our lovely CIS), then your foot is to blame.

Seasons greetings to you and to all listers.
