car running sloppy

hi guys,getting my brothers 94 gt turbo after a long lay off...it has been lying up for some time (2yr)...started it the other day and it has been running really sloppy (jumpy stuttery). what is my first port of call here...ive put new oil ,sparks etc...could it be the fuel pump or injectors ? ive tried to search it but only maintenance advice...it would be still sat up if i hadnt of really pushed for it so any advice would be appreciated.

It cxould well be the fuel pump or something not happy its been disturbed.

Did you put fresh fuel in? This could be a reason if its just been sat up.

has any damp got in anywhere?

have you checked the rotor arm and distributor cap? also the spark plug leads?

probably worth trying an ecu error code check, just to see if that brings anything up. otherwise, it could just be that you need to stick some fresh fuel in the car and run it for a bit. could also be slightly sticky injectors, whilst the car is running, give them a tap, i had an issue with a sticky injector when the car laid up for a while.
