Good day boyz!
Well recently I've been experiencing bad idling, as I observed its either:
1. After starting the car, the idling doesn't go up just below 1000RPM, but it goes and stays just around 500RPM, just like it's about to stall. I rev it a few times, but it still goes back down to around 500RPM, getting erratic, moving slightly up and down.
2. OR more commonly, after starting the car, the idling seems to go fine just below 1000RPM. But, after driving around a bit, shifting a few gears, and going back to neutral while in motion, the idling goes down at around 250-500RPM, the engine shakes a bit like its gonna stall, so I'd always have to shift to a gear to get it up or step on the clutch, hit the brakes and make a full stop, which makes it go up and seem like normal again. However, when I try to drive again, the same thing happens over and over.
Well sometimes on lucky days it doesn't have that symptom, but now I've observed that it happens quite often, like almost everyday. I've learned from reading some threads that what usually causes idling problems is our beloved ICVs, so basically as a result, the ICV is my first suspect. But of course, I need input from you guys if it is really the suspect, and if there are other possible causes too. I also learned before that having sparkplug/high tension wires in bad state may also affect idling. I've read on some places as well that the ignition coil or coilpack may also cause bad idling.
I've got a mechanic coming over in a few days so it would be much better if we don't waste time doing things which may be irrelevant, since I can't do these things by myself
So to finish of my post, here's my questions...
Is it highly probable that the ICV is the one causing this?
Are there any other possible causes of this symptom?
Can the high tension wires or ignition coil really cause bad idling symptoms too?
How would I know the state of the ICV, if I should clean it or replace it instead?
What other things should I ask to be checked and cleaned?
Sorry for quite a long post, but this is really bugging me for quite sometime now. Its terribly hard to drive well when the idling isn't stable.
Thank you guys, hope to hear from you!
