Fault code p30 14

P30 14 stands for throttle valve. Usually, this kind of fault sometimes accelerates "just stepping on the gas pedal". No matter what happens, computers can't compare with them. Initialization can be resumed by computer, the throttle plug can be unplugged, cleaned and plugged in. If the problem still exists, consider changing the throttle plug, and then look at the plug of the intake pressure sensor. This fault can also occur if the contact is poor. Have a good car. If it can't be repaired, you can ask.
