sprevett Posted March 14, 2010 Share Posted March 14, 2010 zed goes for MOT....comes out with engine mgmt warning light on OMG! anyway friendly garagiste mate plugs machine in and gets fault code which says 'engine too lean on one bank' or words to that effect...and then he hears splashy misfire as it idles (which it seems to do now and again....do they all do that?) - so he reckons I may have a fault?! anyway he clears the code and it hasn't come on again...phew... so was it just the horrid MOT man putting it through the emissions check or summat? anyway, car runs just perfick at all times, goes very well....just has a bit of a splashy misfire thing going on now and again...not sure if it started to do it after I fitted Nismo zorst? any ideas anyone?

introspect Posted March 14, 2010 Share Posted March 14, 2010 I'd be careful about just clearing the code, it may get rid of the dash light, but it doesn't fix the underlying issue. I'm no expert, but personally I'd get it checked out, an engine running lean isn't something that should be ignored! Quote Link to comment Share on other sites More sharing options...
doctor austin Posted March 14, 2010 Share Posted March 14, 2010 I had a similar problem when I first bought the 350Z, till someone said leave the aircon on to increase the idle speed a bit...problem solved. Without aircon idle speed 400 to 500 rpm and a bit rough. With aircon 600 to 700 rpm and smooth and clean. They all do that sir! Quote Link to comment Share on other sites More sharing options...
sprevett Posted March 15, 2010 Author Share Posted March 15, 2010 yes i agree about lean = bad, but I assume if it was a persistent problem then the warning light would just come on again? will keep a close eye methinks....and interesting what you say about the AC doc austin...it was off at the time....hmm...will put it back on and see what idle speed does. thanks. By the way what sort of Austin is that? looks a bit like my mates which is a 1924 heavy 12/4....? Quote Link to comment Share on other sites More sharing options...
