..

indicates a failing/ dry clutch throw out bearing
change you habits and place the car in neutral at lights with the foot of the clutch
That will get you a bit of extra time before repairs are required

65NM or 50 psi and do in three stages of torque down

no idea without a drive sorry ,could be anything

the timing mark is often on the bottom pulley and line this up. be careful with your car. my daihatsu sigra used to have some similar problems.

DO IT YOURSELF... It IS fiddly but perfectly do-able.. easiest way to do it is to remove plastic 'dirt shield' from driver's side inner wing (next to drive shaft and brake line) obviously wheel removed, or rotated is ok.. removal of modern plastic 'tat' is simple (area of cylinder head) allowing as much finger access as possible..not much room down the side of these puppies!! Next you need to de-tension the 'serpentine' belt BUT I WOULD RECOMEND DRAWING BELT & PULLEY SET UP FIRST or taking several photos.. as a reminder of if belt goes over or under (makes sense when you see it) Use blunt engineer's screwdriver (or any blunt long driver, rod, etc) to help push and pull old and new belt about.. REMEMBER TO RE-TENSION THE TENSIONING PULLEY...BUT DONT OVER DO IT!! THE BELT WILL TIGHTEN EVEN MORE AFTER SHORT RUN IN.. ALLOW SLIGHT DEFLECTION.. 6 to 10mm should do... cleanliness is the key really, as with all engine jobs(!) Allow 2hrs to do... if you've never done before... ok?

Which three? The same three? differing three? Have you checked the sparking plugs? HT leads? ...Next you need to get an OBD2 reader to plug in and read which cylinder is mis-firing... maybe (usually is!) a coil pack that is on its way out... but double check first.. ok?

drive belt side is one

Your Rocky has a 1.6L 4 cylinder it only has one ignition coil, the coil runs about $75.00 and labor to install is .5 (1/2) hr X there shop labor rate, NAPA part # for ignition coil is # IC135. At my repair shop to remove and replace ignition coil parts and labor no more then $125.00, also I think this is some thing you can do, just unscrew small coil bolts, disconnect harness ans install new one.
