Some say got smell from the part nearby the ECU is located.

Coz it's burnt...

RPM fluctuate.

anything can happen.. depends on what electronic circuit in the ECU is at fault. But usually the check engine light wouldn't go off thats No.1 .. secondly.. car would not start. The most common faulty items in the ECU is the capacitor.. which tends to leak overtime. Replace it with a new 1 before it starts to leak.. leaky capacitors produce some acid... which may make other electronical parts in contact with the acid to be damaged.

Where exactly is the ECU located in the car?

 

[TitanRev]

The ECU location is diff from each manufactures....have to ask ur mech or search by urself loh...

 

[whatdamn]

proton ecus are usually around the glovebox area (left side). just remove the glovebox and look to the left and you will notice a number of wires and a shiny(maybe not) metal box about the size of 2 gardenia slices of bread put together. :D

normally for mitsu/proton rpm fluctuates is because of throttle body is dirty. another thing is the ISC also known as Idle Speed Control is faulty... Proton call this thing "idle servo kit." this bladdy piece of electromechanical shit cost RM1,385.00 part number MD628051 can be ordered from Proton Spare Parts Center. However I'm not sure if it is the same with EVO3. But it is definately the same for all 1.6/1.8 DOHC Mitsu/Proton Engines with 4G9X code. Kedai Potong sell this used servo kit from RM150-300 depending on condition.

i guess will be d idle control system too.....it can be wash by using carburetor or choke cleaner......so it will save ur money if it still can be use after cleaned.....i will try later..thanks...
