Idleing high after upgrading injectors... Fan?
Recently upgraded to 175/30s and my truck has been wanting to idle around 1000 rpms ever since. When i start it and its cold it goes straight to 1000 and stays there until i put it in gear with my foot on the brake.
Going down the road it idles at 1000 until i am almost at a complete stopped.
If i start the truck up and its warm it idles regular like 500 rpm
I heard this was normal from RCD
But I also heard from someone else that it is a issue with the fan?
"its the fan control problem..that control circuit engages the fan when engine is hot and kicks it out of overdrive so the fan can spin faster..it also keeps eng"ine revving so fan pulls air through the radiator..if the connector is broken or not plugged in,,these problems are the result."
anyone know who is right, RCD or Joe Blow?
By the way i still have my egr valve plugged in.
