Hi guys,

I am having an issue with my b18c in my 96 ek4. The engine idles perfectly with no throttle but when the car is revved and held at like 2,500 rpm the car hunts by 100-150rpm which is causing me to fail the nct as the car is overfuelling. Has anyone ever heard of this. I have put a new cat and lambda in the car but still no change, my mechanic has checked all the sensors with a multimeter and he says all sensors are giving him the correct voltage readings and there are no vacuum leaks as it doesnt hunt on idle. Has anyone got any ideas?
 
Throttle cable sticking or IACV? Heard of this when the car gets hot usually in summer time
