2011 Accent AT - Engine Knock!

[bratski]

Thanks for your reply... I'm not sure on the difference between the low power or the fuel knock.. But based on what you said, the latter is somewhat closer on what i have experienced.. If hyundai can not upgrade my ecu anymore, will there be any other remedy? To be honest i'm getting quite disappointed with accent.. Even the fuel consumption.. Sobrang lakas pala sa gas... I'm just getting 7km/L.. Pag traffic 6km/L pa..

You know what? I think what you're describing is my accent, same intermittent delay when sifting from first to second and that loud thud when the second gear kicks in. We even have the same fuel consumption. So cheers, the problems you posted are common among accent a/t's
