Today I fired the 9870 up to flex some edibles and for the first time ever,I had the low engine speed warning come on, it had no power like a dirty airfilter, but, I had no codes,I stopped and checked the air filter and it was dirtier than he??I blew it out and fired it up again, had no power right away but after a few minutes started running like before ,good. what could have been my problem?and why was there no power immediately after cleaning the air filter, shouldn't I have had a warning the filter was plugged, if that was the problem, any answers would be helpful, thanks
