Was the thermostat replaced ?

No. It was not

That is the first thing you try replacing when a vehicle starts overheating.

Thank you... I'm going to try it... Now what about it hesitating to pick up speed???

When a vehicle starts to overheat that will cause the vehicle to hesitate and start to loose speed and will cause the rattling noise you hear because the oil has become overheated and thin causing the bearings to rattle. Once you fix the overheating change oil it has lost its viscosity.

So you don't think that it has anything to do with the converter being clogged???

Could be but really do not think so you can check for a clogged converter be doing this test at night start vehicle and let idle for 15-30 minutes then look underneath vehicle at converter if it is clogged will start to glow red but I am leaning more towards a stuck closed thermostat like I said that should have been the first thing to suspect when a vehicle starts to overheat.

Sounds like there's air trapped in the cooling system. Once refilled the cooling system must be bled. Personally I prefer pulling the cooling system down into a vacuum then refilling it. When the engine overheats the computer begins firing alternate cylinders in a reduced power mode to prevent engine damage. That's why it's shaking, etc. when overheating. A clogged catalytic converter should also trigger the check engine or service engine soon light with a catalytic converter trouble code. You also need to find another mechanic. This guy has no idea of what he's doing!! HTH. -Jim
