2004 Lexus Es330 - Slow Acceleration/hesitation
Posted 21 February 2012 - 04:21 PM
I own a 2004 Lexus ES330, it has ~120k miles on it. I bought the car from a Lexus dealer about 2 years ago, and it was in perfect condition. It was very fast, powerful, and smooth.
Since then, it does not run nearly as well as it did. My main problem is the slow acceleration, when i push the gas pedal the car just doesn't go like it used to. Its slow and there is a 'hesitation' moment where the RPM will go up to but the MPH will basically stand still.
I read that I need to clean the fuel injector and use a fuel injector cleaner with my gas fill-ups. Would this be a simple solution to the problem, and if so what kind of fuel injector cleaner should I use, there are literally dozens of them at the store.
What is the cause of this and how can I fix it? My car is no longer fun to drive and it has taken all of the fun and enjoyment out of owning a Lexus for me.
Thanks for your help, Peter.

Your description of rpms going up but not mph suggests a bad torque converter. If this is the case, then it should be worse going up a hill.
Are you getting a check engine light?
Another thought is, switched out of sport mode?

How do I switch out of sport mode? I wasn't even aware there was a sport mode...
Also, how much can I expect to spend to to get a new torque converter, labor + parts?
