IDLE HELP!
hey guys, i've had my GR for over 2 years now, it's starting to have problems here and there. I've found another problem, it's that the car idles low when car is hot, about less than 500 RPM.
I've bought a second hand Idling speed controller from an import shop on the GOLD COAST, and got new spark plugs in the car, however it still happens. It seems that when i turn on the head lights and fog lights at night, the idling speed drops a little, and if i hold the windows button up (after the windows are shut), the idling also drops as well.
I am wondering if any of you guys have had these problems before? i suspect that the electricity is some how affecting the idling speed, but dont know why. Thanks for helping.

Yygirl,
the possible reasons can be numerous, the simplest thing to look at is the fact your battery may be showing signs of old age and is not keeping the correct amount of charge (which is supplied by the alternator).
Get your battery tested first, and if it's dodgy, replace it.
More importantly, if it's the original battery, or a direct replacement of the original battery, CHUCK IT! Those micro batteries are the pits! I have a 9 plate in mine and it's as strong as an ox.
As I said, there are many reasons for the idle running low (especially when turning on your lights), that's possibly the easiest thing to check for a start (pun intended)
Hopefully it's nothing to do with your alternator, but that can be fixed as well.

Another thought just struck me like a bolt of lightening.
As you had problems and replaced the stepper motor (isc), did you do a computer reset on the FTO?
If not, that's the first thing I would attempt.
All this involves is removing both battery leads (start by removing the red (positive) terminal then the black, and leaving the car totally without power for a minimum of 30 minutes.
This will cause engine management to recheck/reset all systems when powered up again.

one scary moment i had with my FTO was after a car wash and turning on the car, it started to cough and struggles to idle below 500rpms after ignition... (felt like as if the battery was giving way) howver the battery was a brand new replacement...
this went on for about 3 seconds and then it was OK again... any ideas??

yygirl, as I stated in my first post, get your battery checked, eliminate the little things first, your battery could be too small/old to hold enough charge to power the higher wattage globes.YYgirl wrote:Hey guys, my car is idling low again, around 400 in "drive" gear. What are your idling speeds in "Drive"?
This happens at night times when I have my headlights on and fog lights on. I've put in 80watt bulbs. Could that affect it?
During day time, everything is fine, idling around 600 in "D".

mines around the same.. and i have a replaced battery and no idle problems... mine sits around 1,000 revs when idle...YYgirl wrote:oh damn! so what size do you reackon i should get? and it's normally at around 13.5 volts after car started, drops to about 12 when idling at the traffic lights..
and from your post before.. you can fit a bigger battery on the plate thats already there...
as you have reset the ECU, and the battery is "reasonably" new.. i would get someone to check the alternator...
