I think you just wasted your money on a replacement ECU. I dont think those problems are ECU related.

If it worked, great. But those things could have been related to something else ie. cloged fuel filter, pcv, a much needed tune up? Did the check engine light even came on? But if changing the ECU worked, congrats.
It was not cheap..........My mechanic, who is not affiliated with a Lexus Dealership, had to order the part from Lexus. The dealership sent a "remanufactured" ECU, so it was a little less than I originally thought. The part was $918 installed. So far so good!
