[QUOTE="moots, post: 44004, member: 219"] Aiyaaahhhh....yesterday after work,eager to go home,start the car,no crank :angry: ,horn weak,pwr window don't work!Damn battery(Yokohama)!Had it since april 2003.So push started(with help of crs) and dropped by a shop(lucky still open at 1845h).Changed it (rm 150 some cheapo brand) and guess what.....no lah no need to guess........ the "crappy idle once battery disconnected" syndrom is back :angry: :angry: :angry: ! Anyways,once home,I disconnected the battery again to properly clean the battery tray and did: 1.short +ve to -ve leads for 10 mins(to cleanse ecu memory?) 2.switch car on(not start)for 10 mins 3.idled the car for 1/2 hr (this morning)b4 driving NO!Nothing!Nyet!Same crappy idle with the engine dying 3 times(at traffic lights).Well,looks like i'll have to rough it out for the next 2 days then!!! DVNG... I have gone thru the ICV re-positioning thingy but not because of this 'diskonek batt'reason.When I first bought the car(1999),I noticed that the ICV was already positioned wrongly.So I reverted it to normal but the idle was crap. So I put it back(albeit the wrong way).Idle OK at 8k rpm.But in 2003, I gatal again and went to reposition the ICV the correct way.Idle was crap for 1 day and I guess the ecu adapted to this new position and ran fine till now. So if the trick is to re-oriented the ICV,but it still takes 2 days(per yr advise) for the idle to stabilise,then I might just as well let the idle stabilise itself without touching the ICV coz it takes the same number of days to do that.SO.....anyone else with a quicker method? note: I have had the batt disconnected b4 during my early ownership of this car but this crappy idle thing was not there earlier.this came only during the last 2/3 years.
