Accelerator do not respond during the drive

[Ajaya Gurung]

Hi there, My 2007 Yaris Sedan's accelerator do not respond during drive, specially after long drive (sometime after 40 km sometime 250). Have changed fuel pump, spark plugs but problem remain unchanged. The Toyota Dealer could not diagnose the problem. Any suggestions pls !!! :bow:
