2001 Lancer MX Vibrates when about to stop

[evil20angel]

Hello Guys,

Need your help,
Bought a lancer mx 2001, everthing else is seems to be ok,
but ive noticed that everytime im about to stop (or knob on D while stepping on the brake), the engine is greatly vibrating as if mamatayan. RPM down to 500, same as pag liliko.

I ve searched for threads here and saw that the MAF and IACV needs to be cleaned? would this somehow solve this problem?

I have a manual GLS and it doesnt have this problem.
Any input guys would help.

Thanks,

Did u just replace your battery?
If you did, just drive normally, ecu will relearn everything.

Sir Istan,

Ang sabi nung first owner ay nag palit nga sya, about 3 months ago.
Sana nga by this time na re-learn na ng ECU yung change.

So what i did is reset the ECU, disconnecting battery then reconnected, then let the car run for 10 - 15 minutes. so far the symptom is still there, bumababa yung idle approaching a stop.

Thanks,
