Anyone know what could be causing this problem on my r34 rb25det neo - when the car is just idling the revs are really low however it doesn't stall. When you put alot of load on the accelarator and then suddenly step on the break the car will stall/almost stall. I have checked;
Vaccum lines
Serviced the car 10000ks ago
Checked and cleaned AFM
Wondering what it could be? Im thinking a sensor issue... Any ideas would be really helpful.
