What symptoms indicate the throttle body needs replacement?

Several driveability issues commonly point to a failing electronic throttle body. If you encounter warning lights, erratic idle, stalling, or loss of power during acceleration, the throttle assembly should be one of the first components inspected.

• Electronic throttle control (ETC) or check-engine light illumination
• Engine stalls, hard starts, or rough idle at stop
• Hesitation, surging, or uneven acceleration under throttle
• Diagnostic trouble codes related to throttle position sensor (TPS) or idle control

Installation is a typical bolt-on job for technicians and experienced DIYers: disconnect battery, remove intake plumbing, swap the throttle body while preserving gaskets and connectors, then clear codes if necessary. Marsram offers a one-year warranty and recommends confirming fitment with the vehicle-compatibility tool before ordering.

• Simple electrical connector and bolt pattern match OE for straightforward replacement
• Follow safety steps: battery disconnect and intake removal to avoid damage
• Clear engine codes and perform an idle relearn if required by the vehicle
• 1-year warranty backed by Marsram; check vehicle fit confirmation prior to purchase
