Craig1982 Posted October 25, 2016 Share Posted October 25, 2016 Hi guys,your knowledge would be appreciated as I'm new to these cars.i have a fiesta st150 2006.when the engine is warm and I go to start the car it takes about 5 seconds to fire up and the revs are low but clears instantly.it starts straight away with no problems when cold..I find that if I turn the ignition on and pump the throttle peddle a couple of times before starting it that helps but not all the time..yesterday I jumped in the car in a rush with the engine warm and tried fire it up straight away and was lumpy and a message came up on the dash saying something like engine management failure..I switched it off and started it again and it was fine..it has a k and n induction system on it so I'm unsure if it's fuel and air issue?? Thanks in advance Quote Link to comment Share on other sites More sharing options...
btmaldon Posted October 25, 2016 Share Posted October 25, 2016 When were the plugs last checked/changed? If plugs are new the gap may be too big. Has your induction system got a cold air feed? Quote Link to comment Share on other sites More sharing options...
