Sounds like a split I/C hose. Are you still on a top mount? Check the hose that runs to the bottom of the I/C.

Might be the gasket between the IC and hose but the symptoms you describe are exactly what happens when a boost hose blows off a drawthrough MAF based system. If it is truly intermittent then that is a bit strange, but its where I'd start to look.

How have you reset the ecu? The green connectors or battery disconnect?

I'd be inclined to check level and condition of the coolant and oil for signs of one getting into the other.

All hoses for condition and that they're attached, check the intercooler hoses haven't split, look for splits in the air inlet hose and where it attaches to the turbo.

Remove all plugs, checking first that the leads are located and attached firmly. Compare colour, condition, wet/dryness, etc.

While plugs are out, perform a compression check.
