Hi there. Complete newb here when it comes to car mechanics and stuff. Just wondering if you could help me identify an issue with my Si.

It's a '95 1.6 and basically when I start it up in the morning, unless i leave it running for 5 mins or so before setting off it will almost always try and stall on me when I reach the first junction. The revs go below 500 regardless of what gear or whether the clutch is down. If i blip the throttle whilst braking I can save it and if I save it a couple times it'll sort itself out. If it stalls it doesn't restart right away and requires quite a few seconds of starter motor and some playing about with the gas pedal.

Anyone got any ideas?

Clean your MAF (mass air flow sensor - just after the airbox)
Clean your ISCV (idle speed control valve - situated below the throttle body and its awkward to remove, 3 7m bolts)
Could be an air leak making it stall

Could be many things

Have you changed your fuel filter, plugs, leads, or oil since having the car?

Catch me on Facebook as I'm rarely on here.

It probably is in need of a service to be honest, just wondered if there was anything even simpler or not. Is it quite easy to service these cars yourself? (assuming complete newbness)

if you have access to basic tools (socket set etc) then a basic service is easy. just get a air filter, oil filter, sump plug and sump plug washer. (i think) and clean the iscv and maf.

As above, check the air filter too.
