Kevinlow831 Posted February 7, 2022 Report Share Posted February 7, 2022 Hi All. Im new to this Forum and not sure if anyone can help. I have a 2012 Lincoln MKX FWD. I have a "getting worse" juddering under light acceleration, when going uphill and when coming off the gas. I thought this was transmission so have changed fluid twice. Nothing changes Ive replaced spark plugs, air filter, cleaned MAF sensor. It feels like the car is misfiring, so I suspected fuel filter, possible fuel starvation, but I cannot locate a fuel filter? Is it in the tank? I have no EML codes just this juddering and I think a lack of power and response when I accelerate. Does anyone have any ideas? Is there a fuel filter? Many thanks Quote Link to comment Share on other sites More sharing options...

Kevinlow831 Posted February 8, 2022 Author Report Share Posted February 8, 2022 Thank you. I think this is a tank off job, which is not something I can do at home I did have a search about too last night. Could a coil pack be causing this, producing a weak spark?

enigma-2 Posted February 16, 2022 Report Share Posted February 16, 2022 Any misfiring due to coils or faulty Injectors would set a code. Possibly a partly clogged injector not spraying properly? Strange that you're getting a misfire (fuel or electrical) and not setting a code. Does it feel like it's slipping or misfiring? How many miles on your plugs?
