CEL= bank 1 system too lean
where should I start, stock 2003 1.8TQ
recently changed to a 110 BPV and a K&N filter.

any help/advice appreciated.

MAF probably died because of K&N.. replace and see...
I had K&N in there too, and got same result.
Not sure if it was cause and effect or not, but replaced with stock filter, and replaced MAF, and have not had a reoccurance. Bosch MAF is a known weak component anyway.
