ok guys so i just bought a basket case e53... 2002 ,4.4, automatic, 170k miles.. p0343 code was the only code, replaced it with a oem bmw camshaft position sensor. code cleared and then came back within minutes. havent driven it as it runs too rough and sometimes stalls or idles rough and low. also smells rich. but it sounds good when i can get the rpms and idle up.
Does it have a good strong battery in it?
May have gotten two bad parts, or there's a bad ground somewhere. Idk if it's on a relay with other things that work fine or bad relay. Check voltage to and from the unit.
