here a follow up on my performance issue from this tread http://www.m5board.com/vbulletin/e3...s-need-help-new-owner.html?highlight=multiple
so i have been doing tests on menu 4 l/h, its a week i have the car,as soon as i got it i changed air filters i have been getting readings between 90-100 l/h highest i saw was 101 the weather here is pretty cool. Yesterday i put a new fuel filter and no improvement car feels the same and same l/h.
today i found a can of crc mafs cleaner at napa autoparts cleaned them took it for a blast and nothing car is the same.
the wierd thing is i sometimes get higher readings in 2nd gear than 3rd but most i saw today was 98 l/h.
tomorrow i'm going to order new mafs from bimmerzone and going to change spark plugs this weekend and hope i see better numbers
one good thing is i havent gotten a cel light since the first day i pushed it to redline and i had those missfire codes.
so the car hasn't trown any codes but has poor l/h numbers.
