Hi guys!

I’ve got an RS133 that has a weird idle and low rpm issue.. when the car first starts up, the revs drop right down and it seems like it’s going to stall. When it’s driving, when you put your foot down (to pull out at a junction say) the car bogs and again almost stalls..

I’ve tried taking the throttle body off and cleaning it with intake cleaner and it still does the same thing!

Odd thing is, the throttle butterfly only want to do wide open or nothing when the accelerator pedal is pressed down slowly. I’m new to this engine, so I don’t know if that’s how it’s meant to be or if that’s the issue the whole time? The body sounds really weird too.. it’s got this high pitch buzz all the time and clicks like old dial up internet!

Has anyone came across this before and how do you reckon I should proceed? Before I go drop nearly 400 quid on a new throttle body from Eurocarparts!

Thanks in advance

Joosh
