Thanks for reply. My car RPM are 800 with and without AC. Even with all load on like headlights, the idle RPM stays at 800. But problem is that during running when I press the clutch paddle, the RPM drops to 400 and car start jerking for 2 to 3 seconds and after that RPM are readjusted to 800.
I haven't gone to dealership yet. Local ustad was trying to increase the RPM to 1000-1100 by adjusting the screw of accelerator cable. Which I was not convinced.
I search YouTube and found that IAC valve and MAF sensor May cause idle RPM problem. So just wanted to educate my self first regarding the issue.
I will consult some good mechanic also.
Do you have some suggestions. Or guide for good workshop in islamabad???
