When was the last time you have checked your transmission fluid? Only use Toyota Type IV.

2002 gs 300 maintenance idk,i checked the log nothing on the books,but i did get it @ lexus dealership so thinking it came with a inspection.i 'm due on a oil change about 700 miles ago.

Unless its a CPO they didn't have to check anything. As-is no warranty means just that. Sounds like a possible MAF issue as StanCe suggested. You could try cleaning it. Read the DIYs and proceed carefully.
