I had a bad hesitation problem and sometimes the rpm while driving would surge to 3,000. I installed a new throttle body and intake hoses as well as a new MAF sensor. All OEM Toyota parts. The hesitation is gone and most of the time the engine runs good. But now after warm up and the car sits for an hour or so, It has been hard to start or wont start without really flooring the pedal. Once it starts the RPM's go up to 2500-3000. I turn it off and restart the RPM are normal. Starts fine when cold.
