think that possibly you are running with a reduced voltage condition...magnetics are weak for example an injector may not know when to pulse exactly...my recommendation is get a brand new battery, brand new battery cables and wirebrush the area where the second cable to the block attaches~ this way your ECU will not produce errant behavior~
