anparkinson Posted January 26, 2021 Share Posted January 26, 2021 My petrol 1.4 mk6 Fiesta had a crack in the vacuum hose from the front of the block to the throttle body so the tickover and cold starting was a bit erratic. New hose fitted and now starts and ticks over perfectly if stationery. BUT - if i put it into neutral when still rolling the tick-over gets slower the faster I'm going until about 25-30mph when it completely dies immediately. What could be causing this? How could speed in neutral affect tickover? Quote Link to comment Share on other sites More sharing options...

anparkinson Posted January 27, 2021 Author Share Posted January 27, 2021 Semi-auto. The manual transmission controlled by a computer. Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted January 27, 2021 Share Posted January 27, 2021 Have you tried a throttle body reset since the hose was replaced? 1 Quote Link to comment Share on other sites More sharing options...

Yes and it sorted it thanks. I thought it would have relearnt but it obviously needed the reset. Nice to have it back to normal. 1 Quote Link to comment Share on other sites More sharing options...
