Give it a basic service.
Clean air filter, a bit of MAF sensor cleaner in its MAF. Checkout the spark plugs. Replace them would be helpful. Do a clean of the throttle body. A bit of “top end” cleaner through the intake manifold would be of use. If you do choose to replace the spark plugs, you might well have the intake off anyway so give it a good going over with the throttle body cleaner.

Some injector cleaner would be good to drop into the fuel tank.

Disconnect the battery for a while.

Lots of ideas to use here.

only just serviced her last month, new air filter/fuel filter/oil filter/oil/oil pressure sensor/sparks and coils. was running beautifully before the flogging, just bought some maf and air intake cleaner about to do that, will try the injector cleaner too and see how we go then. unrelated question, how often is everyone changing their coolant?
