Can anyone help with a slight problem I have please..had the car for 5 plus years from new with full service at Skoda. Last 2 months had a hesitation in engine power pulling away in first at 1200 rpm and judder if car part warm. Throttle above and it improves, nightmare if in traffic at low speedCleaned throttle body to remove oil deposits and cleaned pressure sensors, slight improvement and using 97 and 99 Ron petroleum improves things. Feels like a fuel come mapping issue. Anyone help please?
