My wife took our Tahoe to a Chevy dealer last week to have diagnostics ran on it. The check engine light has been coming on and going off for some time now. I already changed the O2 sensors already and still the problem exsists. It will run fine some days and others it will hardly idle and die. The dealer gave her codes of P0101, P0171, P0174 and P0300 and told her the catalytic converter was bad. They said it would cost about $700.00 to repair. From what I've read on each of these codes there is no mention of the catalytic converter. Are these codes a dealer only fix or can I do the repairs myself or take it to a small shop that I use when I can't tackle the job myself? I am sending a donation through Paypal for your help. Thanks.

You are correct. The P0101 code is Mass Airfow Sensor perfoprmance, which will set the following 2 codes P0171 and P0174- lean bk1 and lean bk2 which in turn creates the P0300- random cylinder misfire. Sounds like it needs a new MAF, or there is a big vacuum leak between the MAF and the engine

Thanks for your help. I knew there had to be something else wrong since I changed the O2 sensors and was still getting codes for running lean on banks 1 & 2. I will check for a vacuum leak and if none is found I will change the MAF sensor and clear the codes.
