182 idle problems

so i've had this problem since ive had the car and still can't find the problem i'm getting so annoyed i'm consider selling the bloody thing, i keep getting the electrical fault light and the car goes into limp mode, then when i go to stop i put my clutch in the revs drop t about 200 then the car stalls then it starts back up again and the revs are going between 1-2k revs back and forth i have replaced the Tb and the Throttle pedal and nothing has seemed to fix it i'm just tearing my hair out now any suggestions? thanks in advance

Engine management light on ? Get it plugged In and read stored codes ?

Wouldn't bother changing parts until you have had a fault code reader on it as you're just be wasting money
