Greetings all. My EX threw a code today that goes beyond the numbers my book has. It's a P1316 and it feels like it's running on only 6 or 7 cylinders. Chugging. Does anyone know what this is? 

P1316 INDICATES THAT CODES ARE STORED IN THE IDM
l Possible causes:
-- Injector(s) or circuit(s)
-- Open or shorted IDM enable circuit
-- Open/short in EF circuit
-- Open/short in FDCS circuit
-- IDM relay
-- IDM powering circuits
-- IDM
-- PCM
x2Code P1316 Injector circuit and or IDM.
Probably a under valve cover harness has went bad or just came loose.
