I put my car in for a minor service, oil change, air filter cleaned and oiled (K @ N brand) they put in injector cleaner as well. Ever since my car has spluttered. Now when I’m driving the revs pick up for a little bit and go down as well and when it does this it nearly puts me through the windscreen when the revs drop. I put my foot down and no power sometimes. The car will surge sometimes and hunts for a gear. Dangerous to drive. I’m guessing maybe the fuel filter may be blocked or the fuel pump is dying. I know the fuel tank and pump are under the back seat. Does anyone know what else it may be?
Oxygen sensor?
let me know
