    I use Shell again I changed to BP for a coupe fills and the car appeared to run better on the BP but same issue as you I started to get CEL light. Mazda checked and yes fuel related.

    So have gone back to shell and surprise surprise no more CEL's.

    Ok so my CEL keeps intermittently come on and off depending on it's mood

    I have stopped using BP fuel and am using Caltex Vortex. I have been doing so for about 3weeks now, but I feel I am missing some pep out of my car

    I have just gone this morning to clear my CEL again from my dealership and they confirmed it was the same code from before I switched to Caltex. Lean Mixture

    Looks like I am going back to the Shell V-Power again

    For the melbourne members if anyone needs a Dashhawk for error codes and such i have one in the car so just pm me.

    Pete that sucks about the fuel, maybe could be something else like in the tank that contaminates the fuel??? or a slack fuel filter?

    I fill up with BP about 95% of the time and the rest with shell. Never had an issue if you can find a Mobil put some 8000 in see if that fixes her up.

    Hopefully some Flashlube and a good long drive will clear anything up. Otherwise I'll definitely give u a buzz to set up a meet

    Good of you to offer James!!!

    Sucks about the CEL Peter. Sounds a bit odd personally. That's too often. I presume you don't always get fuel from the exact same garage?

    James. I've had the CEL cleared twice by my dealer stating it was bad fuel. Gone back to Shell VPower and have driven my car to Sydney

    On the last full up had to fill up with Shell Premium unleaded (95RON) and the CEL came up again!!

    Might hit u up when I get back home

    Is the car modified in any way? SRI or DP?

    If it's stock then a lean fuel mix can be a worrying sign. Do you know what the error code was? Was it intake or emissions related? The fact it has reoccured kinda eliminates bad fuel as a cause.

    Could you have an air leak? I had a CEL and after retightening all hoses and resetting the ECU - no CEL.

    Hey guys
    It's been 3 months and I had my 50k service and a ECU update and the CEL keeps popping up

    P0132 Fuel Bank Cylinder 1
    Left Bank Lean

    Mazda Dealer has no idea what it might be. They said after the service if it come back on to leave it with them for 4-5 days so they can monitor what is actually causing the problem. They said we know it isn't damaging the vehicle, but just hate knowing that there might be a problem

    Plus I'm a bit hesitant to leave it with since the Service Manager at Garry & Warren Smith Mazda Mulgrave has defected to Berwick Nissan. He was fantastic and honest and always had time for a chat.

    Anyone else had this CEL code or this problem? Everytime its cleared it pops up 1-2 days later

    Do you have an intake or downpipe?

    Tried cleaning your MAF sensor Pete? Might be a long-shot, but from what I can see something's telling your ECU that the engine is running lean (one of the O2 sensors near the cat maybe?)

    If your MAF sensor is dirty, it could be feeding inaccurate data to the ECU about the actual amount of air flow into your engine (ie not metering all of the air passing through) and in turn the ECU isn't feeding enough fuel in to match the actual air rate

    Just a thought

    Thanks mate. I will do that from now on!

    We cleared the code and cleaned the MAF sensor and air filter

    Gonna see what happens after a few days and then speak to Mazda

    Edit:
    Thanks to the advice above, found this website:
    http://www.obd-codes.com/p0171

    Might have fixed it with the cleaning of the MAF and air filter
