Car stutters and lags ?
So I just got my car back from the repair shop , for 240$ they replaced my egr valve and my #1 spark plug. My car runs better now but if I floor it it will stutter and lag with me and kind of skip. Anyone have any good ideas of what this may be , I replaced plugs and wires about 2 months ago and it ran good up until a week ago. Any input to save me paying to have it 'fixed' again helps. Thank you
