My Ride: 2001 BMW 330I
when you guys talk about the lower intake boot, are you talking about the flexible elow behind the mass air flow sensor? I have changed it along with both cam position sensors, new plugs, replaced one coil,(cracked, but seemed to be working),? i am still gettin both upstream O2 sensor codes? Vacuum hoses dont seem to be leaking, but plan on checking CCV next. Engine ran fine after above changes, but has developed the same symptoms again? Loss of power and lhp mode pulling a big hill? Engine runs better with MAF unplugged???? DUH!!! Help??? I need 4 cars running...down to 1...lol
