CAR IS SMOKING AND SPUTTERS

1993 Lexus ES • 167,000 miles

Hello to start I have replaced spark plugs, wires, all valve cover gaskets, oil change, the timing belt has been replaced, oil filter. Now the car drives with little accelration and it sputters with white smoke coming from the tail pipe and traces from under the hood. It smells like exhaust on the inside of the car as well. I was thinking the ECM. Can you help with some suggestions?

Have it pressure checked for a bad intake/head gasket
check fuel pressure and check for a vacuum leak if vacuum is 15" or below at idle suspect clogged converter
