I have a 2017 bobcat t595. It starts fine and idles fine but anything over 1800 rpm it starts running rough. I just did a contamination kit on it because I thought I had a bad injector and had bobcat re code the new injectors. It ran fine after recoding. I let it sit for 2 days and now it's doing the same thing again. After running it for a little while and shutting it off and starting it a couple times it usually clears up and runs fine untill you let it sit for a day and then it starts all over. I checked the bleeder on top of the filter yesterday and it had some air come out, is this normal after the system is primed?
