I went back to Thailand for 1 month and havn't strat my car since, when i got back and start my car, the idle is up and down from 900 rpm to 2000 rpm and keep doing all the times, plus after 2 min. it's stay on 2000 rpm and all light came on etc. check engine, tracktion control and VCA. please help, thank you...

 

Take it for a drive and get on it a few times and see if it clears it self up. If not you will have to take off the Idla Air Control Valve (located on the bottom of the Throttle Body) and clean it. Then reset the ECU to get rid of the CEL lights by pulling the clock back up fuse

 

Thank you very much.

the battery was low on charge from sitting and triggered false lights
dont sweat it

drive an hour, throw some seafoam in half tank of gas to clean crud and moisture.
have electrical system tested at parts store for free after the charging up drive

you can reset the lights by removing CLOCK fuse on passenger end of dash for 1 minute then reinsert--start car
that did a hot reset of the ECU so it relearns and test all the parts
