When was the last time you checked and/or cleaned it?

Maybe 10,000km ago or so, car is only on 55k km, I would say it stays fairly clean due to the location and the small mods I did around the filter, good idea on that though
Just an update, I have since pulled out 3 of 4 ignition coils and did an ohm test on the pins and they seem to come out good so far. I'll try get the 4th out, and maybe even spark plug if possible.
From my last drive the issues occured on very light load application, i.e. full DI so don't think it's a port injector issue also . Anyone have an idea on which sensor would cause such issues if faulty? Maybe map? OČ?
UPDATE: MAF looks alittle oily, thanks Steve, map getting cleaned too. I'll report back if this changes anything
