I recently went through inspection and failed for Cylinders1-3 misfire, Bank 1 too rich and Bank 2 too lean. Also, the code I got, stated could be MAF Sensor and I thing O2 sensor About a month or 2 later, my car oil needle started going crazy and my car was losing power as I drove and surging until it eventually shut off. Car would then idle rough when turned on and then shut off when put in gear. Cleaned MAF Sensor and then got it to run while changing gears, but still rough idle. I out it in neutral after all the smoke clear from my tail pipe and punched the gas then it shut off and hasn't come back on. Anyone know what this could be?

    When we hear of one bank too rich and the other too lean, the first thing that needs to be proven is whether both halves of the engine are pumping air equally. A restricted catalyst on one side could do this, as well as a camshaft that has jumped time (overhead cam engines). Both possibilities can also cause misfires on one bank, and even be responsible for certain MAF sensor performance codes.

    Now the fact that it is no longer running, that is definitely a major concern. A technician skilled in doing compression testing using a pressure transducer and a digital oscilloscope will be your best shoot at having an efficient diagnosis of this problem.

    Thanks.  That definitely sounds like something outside my expertise.  I wad thinking about sucking it up and paying the astronomical diagnostic fee to find whats going wrong and hope I don't get jerked around.

    Nothing like a fresh dose of reality to put things into perspective. Take an individual who has the natural talent that makes him/her capable of being able to learn to be a true master technician. Add fifteen to twenty years of experience on the job past what he/she was capable of as just a DIY'er. Add in the electronics and robotics training and computer skills that rival that of most engineers. Combine that with the dedication to attend a hundred plus hours per year of class-room based continuing education out of their own pocket, on top of the ten to twenty hours a week of self study for their entire career, all while investing around $100,000 into their own tools and watching that investment now be dwarfed by the cost of scan tools and software expense that didn't exist just ten years ago that they must have to work on today's cars. Just imagine doing all of that on a very modest wage and a below average standard of living just to be the best that you can be so that you can be ready to help someone that has a vehicle problem and they walk in the door the first time that you meet them and they give you the above attitude.
