3rd Gen 4R slight engine vibration during idle
Hello,
I've recently been feeling a vibration that seems like it is coming from engine bay. Truck idles at 1200 when started, then rests at about 700 once warm (takes about 10 min). The vibration seems to be present after the truck warms up and idles around the 700-800rpm range. If I turn on heat/fan, the idle jumps to about 850-900 and the vibration goes away. With the foot on brake and truck in Neutral or reverse or even moving slowly, the vibration is still there. Seems like it goes away only at higher rpms..
I checked the engine mounts by looking under hood from driver seat method and they seem ok. I will check trans mount tomorrow. Any other suggestions is greatly appreciated.
Thank you
