Hi there. Under hood temperatures can affect component operation. The hesitation and sudden acceleration (engine warm) could be, a faulty TPS (throttle position sensor) slow to provide a signal to the ECM (engine control module), a faulty MAF (mass airflow) sensor slow to calculate the incoming air to the engine. There are several more possibilities and proper diagnoses should be performed to avoid any unnecessary repairs. I recommend having your vehicle's hesitation and sudden acceleration be diagnosed and repaired by a certified technician, such as one from YourMechanic.
