Hi All,
I'm having the idling problem. During cold/Neutral/AC off is 900rpm. Once temp raise up the rpm increase till 1000rpm. If set back to 850rpm, sometime the rpm drop till 600rpm.
1. ISCV - check the wiring & cleaning - done
2. TPS - check the wiring & set - done
3. CEL - check the error from CEL - no error
What else could i miss-out to resolve this issue?
