i have about 10 x 3 wire ones and 1 x 4 wire one mate and the 2nd lambda should basically mirror the 1st one (but more slowly)Frank, if you do have a lambda could you please let me know. Swapped out the maf for a known working one. Checked the o2 sensor voltage on the Torque app the first one spends alot of time jumping around even at stable revs. It regular shows a lot lower value than the second. So I belive that means it is reading leaner. Damn light still coming on.
a bluetooth dongle thingy and torque app will monitor the short and longterm fueltrims i think mate https://www.micra.org.uk/threads/k11-1-4-cga3de-p0171.63352/#post-714054The only fault code that keeps coming up is p0171
fraid not an airleak would be worse with the throttle shut (high vacuum idle) so the maf wont be seeing that air intake, and wont sense/register itDo you know what the maf at idle should be ?
if the short term trim is stable as you open the throttle i doubt if its a vacuum leak gary,I'll get hold of some easy start to spray round to check for an inlet leak.
It's a pain if it is the maf as I've tried an amazon one and a known working one.
