So last night on my way home from dinner i am cruising at about 2600rpm. everything is fine. it was such a calm night, i increased my rpm's to about 2800-2900 and i get a high pitch whistle noise. i back the throttle down to 2600 again and it goes away. i tried this a couple times and kept getting that same whistle noise at the higher rpm. its not normal that i cruise much above 2600-2700 rpm so not sure if this is new or been there. any sggestions? everything else seems to be operating perfectly fine other than that noise. i scheduled a cummins mechanic to come out tomorrow but if its something easy that i can deal with i would prefer not to pay the $1000 trouble shooting fee.
