Ok i am new to this forum. I gotta question might be dumb, but i am not sure. Ok sometimes when i am accelerating quick and when i am using the power etc button, that most toyota's and lexus comes with, after i do this a few times, when i try accelerating fast again, my engine doesn't do much, i will have the petal to the floor, and it will be acclerating but not fast at all, it wil be at about 2000 rpms, when usually it'll go to 6000 rpms and change gears when i have it floored. Any ideas of what is wrong?

I am guessing that this is an Auto Lexus...

I have experience the same thing. like the auto box can't keep up with the messages from the electronic throttle control ( ECT/ECU)?

Don' t know what its down to. just know I am glad its not permenant. it stops the car from kicking down properly, right?

I had a gearbox switch fault on mine last year. I had been gunning it in real wet weather and on way home from 60 mile trip It would not find the gears properly at all. only let me work through the box manually and even then at set speeds. the reverse light and 4 gear light came on simultaniously...

Took it to Lex and they said it was a switch on the gearbox. had I not "had a good relationship" with the dealership it would have cost alot more than the £400 I paid. Like £200 more!

if you know a reputable auto gearbox specialist. get them to check it out. I am guessing you are not looking to pay dealer prices for diagnostics. you are looking at £75 for them to spend a hour diagnosing it at Lexus. you might get "free" diagnosis at a local specialist.

What I was saying is. if the power loss is only intermitent when you are gunning it through the auto box. it might just be the way you are driving. But if you are troubled by it. the diagnosis route I have outlined is probly the best way to a resolution.

Ps. Welcome to the forum. I dare say, when they wake up, the others will have a few suggestions too. but Lexus is japanese for Lazy, so give it a couple of hours!
