I went out to crank my 307 today and it took it a while to crank which it never does.when I got it cranked it was vibrating badly,wouldn't idle,& wouldn't go over about 2500rpm at full throttle.after a while it began to idle poorly.I let it run for 10-15 min and it didn't really improve.what could it be?bad gas?the gas is new with additive.
