I have owned my Lexus for 5 years now. Regular maintenance always. Just yesterday on a 3 hour trip about an hour in I stopped at the last stoplight thru a small town, when I went to go, she wouldn't accelerate for ****! It took forever to get to 40, then it was fine until climbing a small hill. I started losing miles. That has never happened. I could floor it and she wouldn't shift down. It wasn't consistent though. It would drive normal for a bit, accelerating when stopping and going, then it would be sluggish on the next stop, then start out like normal, but then lose all power when it shifted down after acceleration. I'm stumped!

 

He''s not. I have owned mine for 5 years now. This exact thing just started happening yesterday driving back from the city. Out of nowhere. It's not consistent though. One light, no power, major lag. Loosing miles going up a hill that it didn't have a problem with before. Stop at one light, she drives like normal. The next light, extreme lag until I get up to 60. It would even start out normal, then when she shifted down, that lag came back heavy. I maintain my car's well. I am novice about vehicles, that this one has me stumped!
