Okay I'll try to get something posted after the weather clears up.

It is the same ECM I just had to send it in to get rebuilt because it was causing the idle to fluctuate. I have looked for vacume leaks and have not found anything. It's just odd to me that when I cold start it is quiet and actually sounds like a truck then after a few seconds is sounds like a semi truck... after hurricane Matthew passes over us I will start troubleshooting it and hopefully get it figured out.

Well I just checked the fan and it spins very easily. Is it usuall for the radiator to heat up extreamly fast and get really hot to the touch But it does not over over heat. Of all the vehicles I have owned none of them have ever heated up this fast. If I turn it on and start driving it only takes like 20-30 seconds and it is really hot and then it get loud. Could it be the thermostat?

So I recently changed out my ecm on my 02 SE pathy and it's been running fine except that after it starts it runs quiet and normal for about 30 seconds then the engine gets to opp temp then it is just loud and almost sounds like the fan is working on double time. The engine also heats up extremely quickly but it has not yet over heated. I have tried the idle relearn many times over an extended period but nothing changes. I am just trying to figure out where to start....is it a cooling, air flow, water pump issue, etc... any ideas? Thanks
