My Lexus is250 year 2006 was having trouble catching acceleration. And just now

"It stalled out and would not move into any gear"is a bit vague. Was the check engine light on BEFORE any signs of problems? Get references for a dependable local shop , or invest in a modest ($300.00-600.00) scanner ,that can read LIVE data , along with capabilities to scan other systems besides just the engine. Does it run? -"would not move into any gear."- shifter not moving out of park , or transmission unresponsive in any position?
