_esKYmo_ Posted May 8, 2007 Share Posted May 8, 2007 guys and girls when i drive my escort for roughly 15 mins from cold start and turn motor off when i get to where i am going, the motor sometimes doesn't want to turn off after i turn the key off. it kinda stutters and revs a bit then dies (sometimes maybe 3-4 seconds max). i have been told it may be an automatic choke problem that the car isn't warm enough yet so the choke is still slightly on. any ideas? and how to fix the prob? not a major one but fucks me off none the less. cheers Quote Link to comment Share on other sites More sharing options...
Jebus Posted May 9, 2007 Share Posted May 9, 2007 Once you stop, leave the car idling for like 5 seconds before you turn it off. Wont run on. Quote Link to comment Share on other sites More sharing options...

blakamin Posted May 9, 2007 Share Posted May 9, 2007 its timingeither mess with the dizzy or youre using wrong fuel. something along them lines Pre-ignition? engine too lean? might melt some pistons... if you got timing correct, try colder plugs and some such other shit that someone will shortly explain better than I can coz my memory is fucked Quote Link to comment Share on other sites More sharing options...

Chrome_GT Posted May 9, 2007 Share Posted May 9, 2007 In Short Pre Ignition -google it. Running Hot, heats carbon deposits or sharp edges (ends of valves etc). These hot spots act as another source of ignition, so when you turn of the iginition the hotspots keep it running. The hotspots will also be creating bad flame fronts (leading to detonation) inside the combustion chamber so get it sorted. To fix - try these. a) advance timing. Too later timing means fuel/air charge is still way too hot during the exhaust stroke. richen fuel mix. More fuel means cooler burning c) colder plugs d) remove head and decoke Quote Link to comment Share on other sites More sharing options...
