Cannot Controll Rpm On Pfc Anymore

[Guest ErazeR]

Hi all

i just cleaned my throttle body on an sr20det engine and my rpm went up to 1200 so i droped the car for 2 days and they droped back to 900 or so but i cannot use my pfc to controll them any more.

if i drop to 500 on pfc the rpm just stay at 900 but if i lift them up then they move up.

any idea why it happend like that?

i turned the screw back to 500 and lifted the rpm on pfc and they barely move up and when i drive the car it starts stalling badly.

please help
