Difference between tps & throttle motor sensor on a rb25det neo

[Dbro]

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.

The (actual) TPS is on the (actual) throttle and is what tells the ECU how far open you are pushing the throttle.

The throttle motor position sensor is used by the ECU and ABS/TCS computer to monitor the action of the traction control butterfly (as feedback).

Neither of these are likely to be causing your problem.  IACV is, however.  Clean it.

Thanks alot for your help bro. I havent played around with the IACV before, is it hard to disassemble and clean?
