I recently bought a 2000 Avalon it has 159,000 miles. Car runs good when you first drive it then after it warms up it Runs rough misfires when you put it to the floor it doesn’t want to pick up like it should. I’ve cleaned MAF sensor sprayed maf cleaner through it. Checked for vacuum leak and none of this has helped. Could it be out of time? When car is parked it seems to run fine and not be missing once you get it over 3000 rpms.
