I have a 2000 Kia Sephia with the 1.8 Dohc engine
It all of a sudden started to stall and run real rough. I changed the plugs and it wouldnt start back up.
I changed the catalytic converters, both O2 sensors, Plugs, Plug wires and coils, Camshaft pos sensor. and it still runs like crap. I have to put my foot to the floor to start it and then it idles rough, as a matter of fact it runs rough period.
I checked compression, and i have 200 at all four cylinders. I have what would ppear to be great spark. After it runs for a bit, the plugs have black deposits all over them.powdery black sout.
Also when I connect the OBD2 to my MAC Taskmaster, it tells me ,
Check all grounds
ignition wires unable to communicate. So, I am unable to tell what is wrong with it but the check engine light comes on... Please help

Well...check all your fuses for the no comunication problem with your OBD scan tool. It is usually the cig lighter or the acces power plug fuse that is associated with this. But check them all go be sure. The black soot on the plugs indicates that it is running rich. Way to much fuel. this could be caused by a whole host of things, so go after the OBD no comut problem first. This way you can pull codes and have a place to start on the rest of the problems. Let us know if the fuse is not the issue. If it is report back with codes and we can help. Good luck
