Hi there everyone...I'm trying to help my dad solve this nagging issue about his E30's accelerator.The problem is: you have to exert a lot of force on the accelerator just to depress it from its stationary position, but the rest of the pedal travel is smooth. Basically, when you want to tekan minyak, have to tekan damn hard on the accelerator before it gives way.He's consulted quite a lot of mechs but nobody was able to solve it. My dad also told me that the accelerator became like this after sending it for service one day (long time ago).It's a 320i E30, coupe version.Any feedback would be greatly appreciated.
