问：我有1998年的土星，当我踩油时，它不会加速

您的车辆可能处于降低的功率模式或li行模式。您正在写的问题很常见，以至于特定的诊断，即降低发动机功率诊断is performed by technicians dispatched by YourMechanic. If you request that diagnostic, the responding certified mechanic will get this issue resolved for you. In your circumstance, the vehicle’s powertrain control module (PCM) may have stored one or more diagnostic trouble codes that will identify the "general area" in which the fault lies in the engine management controls. If not, a real time scanner is used to look at actual engine operating data and that will usually reveal enough clues to pinpoint the fault. Although the throttle control system is a common trouble area with reduced power, there are quite a few other components and systems that could come into play and, of course, there is always the possibility of multiple, or "coincident", faults. Here are some of the possibilities that YourMechanic dispatched technicians would consider:

节气门位置缺陷（TP）传感器
有缺陷的氧气传感器
有缺陷的加速器踏板位置（APP）传感器
Loose or damaged wiring
Defective throttle body
Defective powertrain control module (PCM) (not typical; ONLY if a long, long list of other possibilities is ruled out)
Any fault/error that will affect drivability function
Any fault/error that will affect vehicle performance
排放系统中的故障/错误
节气门控制系统中的故障/错误
A fault/error in the transmission control system
