hi all
i drove my teg yesterday , running about 50mph for few miles than i felt the car was shaking , look on the rev gauge it go up and down . than i stopped the car on the side of the road , the engine rev itself from 1k-2.5k and i heard some weired noise from engine bay too..... it didn't happen before , the car runs very well all the time , it had k-pro ecu remapped it few months ago, i'm not sure is it the ecu problem , can anyone give me some advice please ?

Thanks tom

Sounds like IACV but it wouldn't make the car shake. Has the car been sat up?

Take it to your nearest specialist for diagnosis/speak to your tuner would be my advice.

i think you may need a TPS throttle sensor, use flash code see if it flash 7 time?
