Mass Air Flow code and O2 Codes Help!
Have an ultragauge and got p0103 which is value too high and I have a brand new MAF sensor on the disco. Also have too rich codes on Bank A and Bank B. Really confused about the MAF code and what it actually means. I already read the Rave. Can the MAF code cause the o2 sensor codes. It was running too lean now too rich LOL. Qwerky BRIT! Any help greatly appreciated.

Always post the fault code numbers so we have better information.
Your new MAF, is it a Bosch with the exact part number stamped on the barrel like your old one, if not, that is your problem, you can use after market or generic Bosh replacements.

How mechanical are you? The MAF can cause those codes. I would suggest you read in the Rave regarding testing the MAF with an OHM meter.
If you want to double check the correct MAF number, post your part number located on the barrel of the MAF and I'll cross it with mine.
