My 2003 E46 325i is straight piped i have
been driving it for over 1 year never took her
out in the snow but i did it once last week and
started misfiring and when i checked it said
cylinder 4 misfire and i have changed all the
spark plugs and.checked all the coils they are
working any one have any idea what that
could be now its just cranking wont start at
all. I have cleared all the codes when i saw the misfiring codes i dont know if that would make a any difference it was after that it wont start.
Your post/question has been moved here in hopes of getting youi assistance.
Just curious, but how are straight pipes on a longer drive?

I recommend starting by checking fuel pressure. There is a schrader valve (like a tire valve) on the fuel rail, under the plastic cover. You can rent or borrow a fuel pressure gauge from Autozone or similar, if they are open near you. (I don't know where "Barrie" is).
