I need help with this problem as smog is coming up in a couple of weeks and need to get this sorted. It runs fine if the ecu has been reset. Once it has had time to read the sensors for about 15-20 miles it starts to have a rough idle. The idle air control valve, egr valve, dpfe sensor, egr solenoid, spark plugs, plug wires have all been replaced. I have looked for vacuum leaks and dont find any. I am running out of ideas. It only idles rough once it is warmed up. I dont know if it could be the coolant temp sensor. My gauge reads perfectly. Please help. I do not know where to take it next.
