    i have ford freestar 2005 4.2l 6cylinder engine.
    i feel clearly some engine hestitation i have obdii scanner and it show (if i understood well) cylinder 2 is misfiring. i predict it should be spark plug burned on cylinder 2. can someone confirme where is the cylinder number 2? i mean on front near to radiator or behinde near to firewall? is it in middle or on the sides?

    System too lean (Bank 1) P0171 what is that? is that related to P0302 ?
    bank 1 mean cylinder 1 or something else?
    Thanks

    Actually just before that happen i was angry on road to someone so i press hardly on gas pedal (3 seconds) to take a turn. it was idling on 700rmp and while pressing on gas pedal i got 4000rpm, it was so hard,
    i assume it happent because of this
