no it will do it at idle if you cycle the a/c on and off as soon as the engine gets that little bit of a load it will miss a few times then stop but can not pin point the cyl. missing

have you checked back pressure for converter clog? i have had that problem before and also check o2 sensor readings

we have had a code in the past for cyl.#8 at this point we have replaced all coils twice,all spark plugs twice replaced the plug ins for the coils ran compression test,balnce test vacum test i have solus pro scanner wich does not have mode 6 but i have taken it to a freinds shop that has an ocilasco...

2001 lincoln ls 3.9 has an intermitant misfire; it happens under load more than any other time. we have replaced cops, plugs, boots, injector etc....you can be at idle have the a/c off turn the a/c on just to cycle the compessor and there is when it will miss also.

anyone have a clue?
