    check engine lite on all the time, replace idle sensor valve, lite went away, but came back again, the only problem is in the morning, when I start the car, I have to ramp up the throttle for a while. took to dealer, want 1200 to replace the computer and reprogram,

    History: Code P0420 came up after buying car 3 yrs ago at about 90K miles. I replaced the CAT and front O2 Sensor in Bank (1), about $2K for that job. Had to fix failed heated seats and air conditioner beginning of last year. Regular maintenance otherwise.

    Several weeks ago, light comes on (Code P0171 and P0174), then rough idle and hesitation/jumping when first starting engine started. (Air & Fuel not mixing cocrectly). Last week, mechanic replaced failing front O2 sensor and MAF Sensor: $700. Car running better, still a little rough on the idle IMHO. A few days later, P0160 Bank (2) Sensor (2) code pops up, Mechanic says ECM needs to be reprogrammed and both rear O2 sensors need to be replaced due to replacing the MAF per Infiniti bulletin, not a recall. $500 more, and only because he is not charging for the labor. Anyone else have this happen? How do I look up this bulletin? Gaaaahh!

    Similar issues, the mornings are the worst. Check engine light on all the time. Had diagnostic done and came up with code PO-400, whatever that is. Now repair guys says minimum of 300 to remove the throttle body and clear passages then retest. then may have to do EGR valve :(

    intermittent problem

    Occasionally when I try to accelerate in the 30-40 range the car chokes a bit then moves on. When I get to the next light it stalls. I can turn everything off & restart it, but it's very scary. I'm not sure what to do, my mechanic can't replicate the problem despite driving it for a week so no work has been done on it.
