What my problem???
 
Can someone please help me find my issue with this check engine light.

I have a 2001 325i e46. I fail smog and had these part changed and I still get the check engine light after 80 miles of resetting the light. i change the MAF with the air tube and clean the ICV which did not look very bad after having 112k on the car. I also change all 4 O2 sensors. Change of spark plugs also.
I have peake code reader and only two code come up saying E3 and E4 O2 sensor adaptation limit cyl # 1-3 and 4-6.............

What is my issue......please help me....:mad:

take your car to a local parts store that will read the OBDII codes. Better if they can provide the BMW codes which alot of readers will do.

Problem in California is that store ain't allow to do that any more. I was surprise also. Should I just buy a new code reader??

You can get a ODBII reader for around $20 from Amazon. Here is what I have:

What the difference between this one and the ones that are bigger and little more expensive. Does those one give more info, Or does it do the same job?

Check the specifications and find one that will provide manufacturer specific codes. Probably won't be the $20.00 plan.

those are adaptation codes. most likely your car is running lean due to a vacuum leak. probably cvv needs to be changed.
