[DJC MINI]

Hi there,

I think my mini has a very slight misfire. I’ve been told that cleaning or replacing the lambda sensor will help fix this as well as bringing the emmisions down.

Is this true?

Also does anyone have any tips on removing the sensor easily.


Thanks,

Daniel

It’s possible but I would rule out other things first before replacing the lambda.
Is it firing on all cylinders?
Are there sparks at each of the plugs?
Have you checked the lambda values with diagnostics equipment?

What about tight vac hoses? The rubber/plastic angles of the original vac hoses always make tzrouble. I replaced them 34 years ago with colored silicone tubes.  After that misfiring had gone.

While on the subject of capilary tubes and fuel traps, there is a known problem of fuel causing blockage in these tubes, mainly the one identified with green, attached to the long green port of the fuel trap and the ECU at the other end. The symptoms of this are, hesitation when accelerating usualy acompanied with a backfire in the inlet manifold and the car usualy bucks violently." ( Hints from
