???abnormal?
Test on another car and try to get the code.

Code 14- iacv
Code 20- eld.

14 needs to solve if not idling up and down.
Check the related transistor to iacv.

20 should not be a problem...

 

[iceman401]

the idling was fluctuating up and down. when the car is cold, start and the rpm was too low ard 500rpm that it dies off all the time. so everytime start up need step on the throttle to give some gas. problem of the iacv solenoid?

 

[E-Tech]

Iceman...
COnfirm the iacv solenoid with a good unit first to confirm.
Is still cannot maybe got conponent in the ecu burnt.
Tq

changed all the caps.still same problem.

help pls.

 

[iceman401]

replace ic17

IC17 ? what is the function? part number?

I found some related thread they say its the QM3 STA412A

can you verify?

many thanks

Ha ha ha....
Ur symptom Cel take long time to off?
If Cel off can start. If on cannot start?
Yes-->ic17.

STA have burn mark?

 

[ryand]

it usually starts when you plug in the ecu cell comes of instantly and i hear the relat but turn it off and on again sometimes it still works ok and starts. but sometimes cell wont come off and no relay sound.

change all the caps.
