2006 Nissan Serena MR20DE slight misfire, no codes. was created by Desmond6004
I bought this vehicle 8 months ago and it has gone well until about a month ago when I started to notice a slight 'misfire' under very light acceleration.
I'm not 100% sure if it's a misfire or something to do with the transmission but I can feel it as low as 45km/hr as I touch the pedal and it starts picking up to 50 km/hr
then I feel 2 or 3 misses or jolts in the transmission. Initially I couldn't feel it at higher speeds but now it's becoming more regular - I would have pulled the plugs out
to have a look at them long ago if it didn't involve removing the intake manifold.
I scanned it with my Launch CRP123X and found no fault codes in the ECU or A/T module.
This is a snapshot of the O2 sensors working - the misfire was happening most of the time but a lot near the end of the pattern.
