Salam Pakwheelers,
I'm facing a problem regarding idling of my 2004 Accord CL7. So, the problem is whenever I start the cold engine the rpm goes to 1300 but idles very roughly (along with black smoke from exhaust) and then suddenly goes to 2800+ rpm with no black smoke, remains there for a 30-45 seconds and then starts to fluctuate rpm between 1000-1500.
I have changed its throttle body but the problem here continued. After that I recently opened throttle body and cleaned Idle Control Sensor but there is no change the problem is still present. Please help me out and let me know what could be the problem here. Thank you!
