“City street ...pressed on gas after the light changed and it did not go forward and then waivered for awhile. I was very close to home. I do not know how it will work tomorrow . No warning lights were on. It has acted funny before like this on highway trips and then it wouldn't do it. Toyota dealers do not even know about them and it is annoying. It feels like a transmission slipping but has less than 70,000 miles. I thought maybe heat is doing it but now that it is out of warranty ie over 5 years old, I do not know what to do. …”
