[QUOTE="iphoein, post: 427857, member: 19525"] Hi badmd, if your car symptom is that it will start but need to press pedal to maintain rpm if not will die, then most probably is ICV. Unless the ICV crack or damage, it can be service, i.e. clean it. The ICV is a valve as the name suggest with a moving part inside similar to those ball valve we use in the house plumbing. After a while, it will be clog/full of carbon/dust deposit stuck to it impending its movement and it need to be clean, and I meant clean it and not just spray it. If you just spray it, it won't last very long. You might as well need to service the whole throttle body as carbon/dust build up will also affect it. Other wise change it, cost abt RM700. [/QUOTE]
