Although usually fuel problems are actually electrical problems, check for a vacuum leak, hissing around the intake manifolds, and the acknowledged test is to carry out aimed squirts of WD40 at the joins in the manifold and see if the revs rise or fall.
after that check the idle air control and the Mass airflow sensor, and definitely clean the MAF if you haven't done so recently...
it is the sign of the clutch wear surely. Do not delay the replacement because the slip you have burns the clutch with the flywheel overheated and will crack to need renewal which it is very expensive part. Also there is not any adjustment on it,it is a self adjusted clutch system.
Depending on the range of rise and fall, this is completely normal. Oil thins out as it gets hot so you will notice the pressure drop significantly at hot idle. A typical value would be 20psi, then as the engine revs up, the pump creates more pressure because it can now keep up with and exceed the leak-down or bleed-off from the bearings. The maximum pressure would be limited by the relief valve in the oil pump which could typically be as high as 60psi.
