will this cause flucuating fuel pressure readings??
ok, batch fire means that more then one injector is firing at once right? which to my simple mind makes no since, because wouldn't that cause bad MPG?? well either way, would batch fire cause the fuel pressure to fluctuate, or should if be smooth and constant? my readings kind look like that of vaccum readings on a engine with a bad valve, just barley fluctuating, but quickly.

Mine never fluctuated. I suppose either you have a bad fp gauge or something is wrong with your pump or regulator. And yes, I always thought batch fire was kinda sloppy too.
