Clio 182
Hi,
Having trouble passing NCT (Irish MOT) on emissions on my 182. One obvious problem is the dephaser is not well. Put a litre or so of Lucas Heavy Duty Oil Stabiliser in and noise stopped and passed an independant gas analysis. Two weeks later it failed the NCT on Lambda 1.07.
Tonight I did a few recorded scans on my Autel 539b. I scanned both o2's and both STFT's. Also added LTFT to the scan. The data was quite random. The only repeatables were post o2 stft at -100% and overall ltft at -4.7%. All the others varied over five tests. First few tests on post cat had voltage unmoving at 0.410 (stft also at -100%). I
know this is a bit of a minefield but if any of this makes sense to anyone let me know before she goes of the harbour wall!
Thanks!!
Alan.
