#8 cylinder misfiring
 

went to change plugg for first time after buying.......all went well till i got to #8..whoever put it in last broke it so the top half of the plug came out and left the bottom half in...had to order special plug removing tool...finally got it out.....now its misfiring in that same cylinder!!!! changed the coil and nothing happened!!!??? its really bad shaking all over not ideling well and even dies while in gear if not giving gas??? what next???

remove the new plug and look. it was not the last person to install the plug it was the plugs are a joke and break easy.

and look at what???

the plugs are good now we put new ones in....now its misfiring and engine light is still on

Very possible it could be a bad injector , there is a recall on the injectors .Google ford fuel injectors.

look at the new plug. just because its new does not mean its good. see if its black or if you cracked it when installing. could be an injector but i thought they throw more codes than just a single cylinder misfire. they screw with the o2 readings. before i go to far with injectors i would pull the plug since its new it should not break

ya we pulled the plug last night and it looked fine.....idk
