forund problem ?

What is your question?

check engine light on and runs rough. it stopped and will not start. turns over no spark Changed crank sensor nothing changed cam sensor started stopped while blowing ASD fuse changed spark plugs and air filter found bad igniton coil changed it then it started and ran rough as before it shut down. checked all relays and they are good. started and run rough then smoothed out then it acted like a load was being put on it like the AC but it was not on. after it started doing that the same coil had smoke coming out so i shut it down before it blew the coil any suggestions on what could be causing this ? Thanks
