Not sure if this is the case but Focus injectors were semi direct replacements back in the day for the hot rodders. They had many more smaller holes and flowed more fuel: your 16-19 rate. Converted my ranger to electric so lost interest, but pulse width was really important. Figure you have mismatched set and one isn't seeing enough to fire every so often. Otoh, I recall my fuel regulation was 50 psi rock solid across several different measuring schemes
