what are symptoms of clogged fuel injectors?Acoustic cleaning is an effecient way of cleaning injectors?

hesitations, lack of power, intermittent missfires and a lot more.

I prefer the direct injection of a cleaner through the fuel rail. we do it a lot and have great results with performance increases and increase in mileage.

what issues go you have??

what is meant by hesitations?m only havng issues wd idle RPM they stay low at 700 rather than 800.i purchase thz car as 2nd hand and when i bought it its RPM was 200 engine was stalling. mechanic cleaned its throttle body bt mechanic was nt from toyota a local one.now i will go to toyota dealer and let the throttle cleaned by them.thanx

you dont have to be a toyota tech to clean a throttle body.

It may be the throttle body itself that may be a t fault but you are doing right by getting it confirmed.
