yea ive ran some basic injector cleaning which causes car to run better and issue to happen less, but whats making mean lean towards battery being at least part of the issue is that if i keep gas level above 1/4 the issue happens a lot less and is a lot less notiveable when it does happen, if has gets lower than 1/4 the issue gets worst and seems to happen almost every acceleration, im thinkng when gas is low like that it takes both fuel pumps being on to move gas which takes power away from engine parts sane as if i add ac into mix again pulling more power away from things, but could batt really cause rpm fluation like this?

@Jnelson1182 I swear I'd use a BMW Code Reader that has a diagnostics mode. Just saying.
