Engine Loss Power

Hi guy,

For some months I have a problem with my lexus IS200 AUTO .

When I press full throttle revs until 2500 and suddenly falls on 1000 revs and then climb normally.

Also when I want to overtake another car and switch from the 4 speed to 3 speed revs in 4500 and then rising up to the 5500 revolutions and then shifting rules.

I've taken the car to mechanical and has check through everything but did not find the problem.

Someone has something to propose because I'm desperate.

Thanks,

ignatiosm

You need to have the diagnostic codes read before doing anything else, where are you from?
